First Mod: Headers or Shark Injector?

[Smolck]

So I am finally to the point of mods for my car (after almost $4700 in maintenance over the last 21 months!). First mod is either headers or shark injector. Sooner or later I will get both, but for now can only do one. Only "mod" the car has now is a 3.46 diff.

If it was your car, which one?

[NorCal-Dimitri]

I'm considering the same mods. I feeling headers. How do you like the 3.46 diff?

[danewilson77]

Headers, exhaust, intake then a Eurocharged tune.

Surprised to hear you say Eurocharged when you have Conforti. Any particular reason?

3.46 makes the car what it should be from BMW. It is slightly slower in the 0-60 category because you have to shift to third to make it, but both second and third gears are a monster and the overall 1/4 mile times are better by .3 seconds. And passing on the highway no longer requires downshifting to 5th.

[danewilson77]

They can tune it to your mods. It's a better tune. I only have AFE intake and no exhaust moss so Shark packaged tune made sense to me at time and I didn't even know about them either.

I will be going Eurocharged tune when I do my headers and exhaust.

I liked the shark I had on my 323 with an intake. Felt nice on that little engine.

I guess I just like the DIY nature of the shark vs having to send off my DME. And I have never seen any head to head dyno pulls with a normal software on a modded car (headers, intake etc) vs one that has the software "tuned" for the mods. I mean, it can't add THAT much more power, can it?

Also, I doubt I will ever do exhaust. Too much money and would be way too loud with headers.

[BCS_ZHP]

Smolck's,
Think of it in 3 parts - breathing, drinking, & exhausting. You need to do all 3 to maximize your performance increase. But as Dane said, try not to do one (Shark) that you might have to change or modify after the others. The intake & exhaust changes are pure mechanical, do those first as you see fit and to your desires. Then afterwards you should be able to feel if its lacking in low end torque and/or high end speed, and at that point any of the custom tuners should be able to give you what you want.

I was in the same boat as you. I was able to find a set of BimmerBrake headers for fairly cheap, so I pulled the trigger. I probably won't have the time to install them for a bit, but I'm still happy with the stock exhaust, so no problems there at them moment.

I went with the 3.38 over the 3.46, but we'd have a similar setup, so I'd be interested in hearing your input on the setup if you go the header route.

I agree. 3.62 is even more fun haha.

Are you considering a full header-back exhaust? Cause it feels like a bottleneck will be your exhaust if you get headers. In California, I have issues with dealing with smog check. I personally would go with a eurocharged tune so when you do get the headers, you can get a new tune again for the headers.

[328ioc]

I love my Shark but I will admit that when I do my headers I will be switching over to a Eurocharged as well for two reasons.

First being what Dane said that it will be customizable.

Second being that Conforti does not offer a cat-less tune for the 330. So you will get a check engine light.

Every time I talk to Turner about this I get the same generic answer of "a new file for headers is coming soon", it's been almost a year and I keep getting the run around. So bye bye Shark and hello Eurocharged.

So now I am in a real pickle, cash is available for intake or headers. I just have to pick one. I'm leaning toward intake for three reasons (what do you all think of my rationale?)

1. Super easy install (unlike headers which I have done before, but still takes 5 hours)
2. No CEL
3. No obnoxious sound and will compliment the software when I get it. If I like the gains, I may stop there and not go the header route due to noise, smell, and general hassle.

My point is, of all the mods I am more on the fence about the headers than anything else, I just don't want to destroy daily live-ability just for 10hp. So maybe starting with the other things is better?

Thoughts?

I agree with your logic. I would love headers but don't want the CEL and potential hassle involved with that. Not to mention headers with high flow cats are stupid expensive

[328ioc]

I agree as well which is why I have everything BUT headers even though I consider them everyday.

Personally I think an intake is a great first step.

Performance changes with and intake or a tune won't be massively noticeable.

But the sound coming from an intake is very noticeable, very intoxicating and worth every penny IMO.

Sway bars and Z4M offset thrust bushings

What do the z4m offset thrust bushings do? I don't even know what those are... sorry for being a noob. I have sway bars, and am all about handling over speed (first).

[Hermes]

They increase caster in the front wheels.

I got the idea from my buddy with an E30 325i who put E30 M3 offset bushings on his car, then realized the Z4M ones work for us in the same way

[LivesNearCostco]

More caster gives you more negative camber on the outside wheel when in a turn, without giving more negative camber when going straight or braking. This should in theory give you better front-end grip when cornering without accelerating inner shoulder wear on front tires. Only possible downside is more steering effort at speed and offset bushings move tires forward in wheel well.

I'm thinking of upgrading my camber plates to get more caster.

Interesting... may be another project for me...

So quick update: My ZHP has been giving me issues lately. As in, NO power at all. No codes mind you, just no power. I mean, I timed it at 0-60 in 9.1 seconds!

Turns out, my MAF was bad. Replaced it with an el cheapo from ebay which didn't work (CEL, no idle, el crapola) and then had to buy the big dog OEM MAF for $300 clams. Add a ticket and my software/intake/header slush fund is wiped out.

BUT, I have decided to go the Shark route when I rebuild my fund.

Thanks for the feedback gents!

[danewilson77]

So....your loss of power was fixed with oem MAF sensor? You didn't have any codes either?

Did you try cleaning your old one first (I assume you did)?

It was an odyssey that almost made me sell my car and lasted several weeks. In fact, I posted this thread in the midst, thinking the software would make me run better. Long, Long, Long story short:

Noticed the car was weak past 4k RPM. Built revs in a linear fashion, but just no power. Backed this up with 0-60 runs in the high 8's and low 9's (BAD). Car has ZERO check engine lights and no stored codes.

Replaced 90k mile Bosch plugs with NGKBKR6EQUP (slight increase)
Cleaned MAF (no change)
Seafoamed (no increase)
Replaced Beisan VANOS seals with 100k miles with new Beisan VANOS seals (slight increase)
Replaced DISA flapper with GAS rebuild kit (no improvement in power, obvious improvement in design, it is a great kit)
Replaced pre-cat 02 sensors (made it worse)
Here is where the car started to chug a little at part throttle in 4th gear which started me thinking MAF
Reset adaptations (no increase)
Lubro Moly Engine Flushed during oil change (made my clogged CVV start working again, no power added)

Lightbulb went on! "hey dummy, unplug the MAF, you have a manual trans and can drive it like that and see what happens"
P-O-W-E-R!!!!!!
Instantly the revs built hard and fast again, she drove WAY faster. 0-60 times back to 6 seconds or so.....
Installed cheap Fleabay MAF, still made power but got CEL for MAF voltage too high and the car wouldn't idle (sent back)
Bought OEM MAF and problem solved. ALL power restored, car runs great (and it should, EVERYTHING power related is new), and my MPG's is above 24avg.

Being smarter and troubleshooting the MAF sooner would have saved me a bunch of time and money. Current amount this car has cost me in 22 months $4,986.24 in PARTS ONLY! (I am my own labor)

OUCH! But hey, it's paid for!

Yes, I got a p0103 which I think is MAF below temp or something. I also got an intake temp sensor code (p0113 I think). But the car ran STRONG and I drove it like that for a few days till the new MAF made it.

So headers/exhaust are seem to be the biggest power maker on this car? Am I correct in assuming that TMS or Rogue Pulleys won't do much? I don't have big power-mod plans for this car, but like everyone else, I'd like a little more oomph. I figured an intake, shark, and pulleys might give me a little more punch.

TMS pulleys make a significant difference, I've driven a ZHP with Dinan throttle body and stage III software. It was a dog compared to my ZHP with the turner pulleys & Dinan CAI

Funny, I was about to say pulley's don't make much of a diff, and most (not all) people I've spoken with or read about say the same. They didn't to me... glad you had a different experience. As far as non FI, headers are the most bang for the buck from everything I've read. But I think you'd need a tune to remove the CEL lights that come on due to those IIRC.

There is always going to be somewhat of a difference between vehicles. My ZHP is a dog compared to most normal 330's. I think I got a "slow" one. I have seen some stock ZHP's dyno as low as 184hp at the wheels and as high as 210. So you probably are one of the lucky ones and got a strong motor.

By the way, I ended up doing an intake first. The sound is a blast. In the next few weeks I will be doing a EuroCharge tune. I will update the thread then. If that doesn't satisfy my blood lust for power, I will get headers and a re-tune. After that, if it is still too weak, I'll light the car on fire and give up.

I just thought the software would be easier. For one, I don't have to deal with my exhaust right now (it be cold outside for us Bama boys) and two, if the tune does what I hope, I may not need the headers and the smells and noise.

Thoughts? I have cash in hand, just waiting to spend it.

[johnrando]

The tune should def help... you'll want that anyway regardless to take advantage of the headers, so you might as well get that first. If you like it, you're set. If not, add the headers and then get the tune adjusted for it. I don't know what Eurocharged charges for a tune adjustment but I've seen others and it's cheap, like $50.

I think Seth said it is no charge to upgrade to the header tune. I agree with you, but I am wondering now if my cats aren't somewhat clogged. Headers might make a BIG difference. Even though they are loud, smelly, and a bitch to install.

Shark and Eurocharged are different. From my research Eurocharged is the way to go because it can be modified to your specs, not a preset tune. It can also be setup for your mods to maximize power. And the best part, with the ZHP Mafia discount, it's $300 bucks. Cheaper than shark

I haven't yet. Ordered some, but they were on back order so I decided to go this route first. I have credible sources that tell me the ZHP factory exhaust with headers is insanely raspy. I do not want a race car, this is my DD. My guess is the tune, while only good for maybe 10 PEAK HP will give me even more in the mid range and that is what I want. Headers typically dyno at 12-15hp too so they are both good. But the tune might satisfy my blood lust for power without the need for a day long DIY and smells and loud noises (it is a ZHP after all and not my Uncle Frank, he is full of smells and sounds too)

[UdubBadger]

The headers combo with tune is good for about 25 peak.


If you look at my old Zhp build thread I had stock Zhp exhaust and it wasn't as raspy as you'd think - nowhere even close to how raspy my M3 is now with headers. The Zhp with headers and the TSE3 it was too much.

It's nice with the magnaflow but you for sure want the resonators cuz the magnaflow has a straight through design so you'll get tons of rasp without them. It'd be like straight piping the car basically.

This is true. I think I will experiment with the resonator first then go from there.

Also, Seth is more of the expert but in my opinion I think the tune first is a good idea because then your car is fully ready for headers and you don't need to deal with a check engine light or anything like that. Just throw on the headers and go make noise.

I just think tune because MAYBE you won't want headers and it's a long DIY or 5-6 hrs of labor you need to pay for and then mess with emissions and all that. It's possible that Just a tune could be enough to satisfy you. If you do headers first your not really maximizing it's gains without the tune anyway so you're only getting 1/2 of what you pay for. You get better flow with headers but they also allow you to push the engine further which is why you'd want to tune it as well.

And just to be clear again, the tune does NOT wipe out the CEL on the zhp. You need to buy an LS-1 wideband controller to do that and pass the electronic emissions readiness test.

I know it isn't an M3. However, after a tune and catback I think my 0-60 time will be darn close (3.46 diff helps). This morning I got a 5.8 with a decent amount of wheel spin. But having driven several M3's I can assure you I have no illusions of M3 speed. But you have to remember, my car was beaten by a 323 automatic with 300k miles recently due to the clogged cats. So to me, it feels like a Ferrari 430!

I agree. My buddy has an M3 and it pulls as hard at 120 as the ZHP does at 80. And 8000rpm is soooo much fun. But the ZHP is PAID FOR!

So I am going to squeeze every last ounce out of it I can. Tune, pullies, cat back, and thats about it. I may go the route of FI one day, but not until I have another DD.

And again, I'll say, while the rasp is a bit annoying and the CEL (though that has been fixed) and the smell, it is 100% worth it. PERIOD. The car now runs as it should. If I had smog inspection in my state, I'd still do it and put high flow cats down stream or even swap manifolds come certification time. It is THAT worthwhile IMO.

For two years I have said it wasn't worth it, not worth doing, etc, etc. I was WRONG!

Yea, I guess I should have specified, I meant bolt ons. I have plans to buy a low mileage short block and add the VAC head and cams, but again, this car is a DD through at least the next 2 years. I need reliability more than speed.

I could have bought an M so many times, but with the miles I drive (40k per year) it is expensive and not practical. And again, the ZHP is PAID FOR!

I can attest. Having done normal 330 header swaps and now my ZHP there is no question the headers let the cams do what they do and you feel it a lot more than the normal 330. However, I am running rich and can't wait to get my tune. Car is a screamer though. I just beat an 08 mustang GT from stoplight to 80mph by half car. He ran away at the top, cause 300hp is gonna win at those speeds, but I was impressed.

A tune can only help!

I need to take a ride in a intake/header/exhaust/pulleys/tuned ZHP. Anyone near me with these mods?

I frequent the DC Metro area (Rockville) as well.

[Smolck]

Well for me, smog isn't an issue. We have no such tests or even a state inspection in AL.

Car continues to be an animal. I bought some E92 wheels tonight and bolted them on. Seems an appropriate upgrade for the old girl. Even from a roll in 1st the car will spin the wheels most of the way through 1st gear (even with new tires) and grab HARD in 2nd. The 3.46 diff has come ALIVE with the extra power of the headers. Hammer it in 2nd and the nose rises, the ass plants, and she digs to 58mph in a hurry!

I have owned the car for 2 years, why oh why did I wait so LONG! This adds the edge those E36 M3's have that I love. You get the rawness of the E36 M3, but the niceties of the E46 design. Tune and LSD here we come! I want MOAR!

Oh, its worth it. Even the slight smell in the drivethrough is forgotten when you romp the throttle and the car takes off. I know my cats were clogged, but even a perfectly working OE manifold is sooooo restrictive. When I pulled my cats apart, I found that the three pinched runners feed in to a single 1" pipe and then to the cat. 1"! A car is an air pump, and it is choked to death with the stock manifolds. The ZHP makes a ton more power because with the increased flow the cams really are allowed to do their job (move more air).

Also, as promised, here are my E92's........

First, Smolck, looks great. Really good to hear those headers are working out.

So, I say go with the injector first as that's true improvement in power, MPG (hopefully), and overall responsiveness. Then, absolutely add the SB. It improves throttle responsiveness and allows you to get to that power quicker. It's definitely not overkill. Many who have it will attest to that. I have an AA tune, and I tell people to drive it w/SB on and off, and they all are amazed at the difference. Curtis (SC4ME) just drove mine yesterday and he can attest as well.

My throttle response is already pretty good with the headers. I was only kidding about sprint or pedalbox. For a slightly stock car, they likely have some merit. For mine, I don't see the need.

This is correct.

No need for full exhaust either, sounds great with zhp exhaust. Magnaflow is the only aftermarket if recommend, it's LOUD.

As far as some 200 or 400 cells you can always just get some welded into stock section 1. You'll still need an LC-1 though.

Would the stock exhaust be too restrictive and defeat the purpose of the Headers? I know that we do want to keep some back pressure but I feel like I should maximize the gains w/ a proper exhaust.

BTW - I think it was your car I saw (Ti 330?) with BB gen3 headers and some exhaust....it was LOUD lol. Might be too loud for me. I'd like to keep it rather subdued until I get on the happy pedal.

Stock exhaust isn't the restriction, the stock manifolds are and once removed, you will be amazed. My car begins to rasp at 3000rpm. Inside with the windows up, I can hardly tell anything is different below 3500. Romp it and things get exciting. To me, sounds a lot like a stock m3, just perfect

Remains to be seen. I just don't know. But the installation would be a cinch. One thing I wonder though, even with post cat 02 sensors, would you still have a CEL.

Can you run the headers with plug non-fouler and avoid the CEL? Another question is could you run the headers without the tune for a prolonged period? I realize you would not get the full benefits of the headers without tune, but just curious. I have also read a large amount of threads about CAI vs. stock box vs stock box with drop in, I think I would prefer to just keep stock box with drop in. Is this enough "flow" to feed the new headers? Sorry if off-topic somewhat...and I love the videos SMOLCK they made me want headers.

OEM box is not a bottleneck. You don't even need a new filter to keep up. You could upgrade and gain 1hp-3hp, but I don't believe that is related to exhaust flow.

You can run without a tune a long as you want, it's just better with a tune.

You get plenty from the headers with no tune, but much of the gains are above 5000rpm. The tune brings more midrange from what I researched. Regardless, it is not required to run headers.

Some guys have success with the defouler, some don't. I don't care enough to fool with it. I will get the tune, then get the LC-1 and call it good.

You don't need a cold air intake either. You will get a decent gain with headers though, but still less than 10hp. If you go eurocharged they can set you a tune to account for the stock air box.

The benefits far outweigh the problems associated with headers IMO.

[UdubBadger]

Our tune recommends at least a drop in filter. Stock paper is quite restrictive of necessary airflow

Today I took the previous owner of my car for a ride in the ZHP. He sold it to me with 138k miles and the converters weren't clogged at that time. In other words he owned it when it still had full power. After the 3.46 diff and headers the car is much better. I ran it up to about 3000rpm in 1st gear and laid the hammer down. He was astonished!

Anyone who uses a decent amount of oil and has over 150k miles on their OE cats has issues. I guarantee it

So I pulled a Smolck...filming a 0-60 with one hand. LOL. I try to hold the camera with my hand on the steering wheel and should I need more steering input it's easy to release the phone and be 100% on steering. I got a really decent launch as my "Dunlop 3D Winter Performance" tires just chhhh chhhh chhhh'ed for a split second before grabbing in 40F weather. With summers I could get a lot more power down on the ground but is this pretty normal for my setup?

I counted between 6.5 and 7 seconds. Not too shabby for an older car. Ditch the cats and buy headers and you will pass out from the extra power!

Before I toasted my diff I got a 5.6 sec 0-60 time. That is a 3.46 and headers too. I honestly think with a tune I will be in E46 M3 territory, at least to 60mph.

[UdubBadger]

U think wrong and I say that because I too underestimated how damn quick a stock m3 really is...

Catless Zhp with a tune is really quick but the M3 just goes balls out and doesn't quit. It's kinda scary.

Well the numbers are the numbers. Stock M3 0-60 is 5.4 sec. I'm close to that now.

Again, I know you have an m3 and I am to trying to start a pissing contest. Just saying that from 0-60 they are similar. I've driven a bunch of m3s too, I know they are much quicker, one only needs to look at the 1/4 mile times to know that. But 0-60 is a different deal. The m3 is just hitting the good part at 60mph.

[UdubBadger]

No no no, don't get me wrong, I'm saying in good spirits.
I totally thought that too at first but they feel so different to me in real life. That's all.

Wrap or Coating for the headers?

The headers I have are already wrapped but would it be better to get them coated for ~$300? This place (http://www.jet-hot.com/) is relatively local to me and obviously it'd look a lot better than the wrap but is it worth the coin?


The headers

[UdubBadger]

I never really saw the benefit. Wrap is likely enough.


Goin' HAM mobile

[Smolck]

I didn't wrap or coat my headers. Seems fine to me. No better or worse than the factory manifolds from a heat perspective. No difference in performance than a buddy who has headers and paid $300 to get them coated. In fact, I am faster!

[TigerTater]

Smolck....

I viewed your videos on youtube trying to get a feel for what the ZHP sounds like with headers and stock zhp exhaust, but couldn't really tell what it sounded like from outside..Would you mind maybe doing an outside video of start up and some revs or even a drive by?? I want headers just want to make sure its the sound I'ml looking for. Did you go eBay style ?

Also...what all did you replace when you installed your headers...like the gaskets, head bolts, nuts, heat shield, etc, OEM, p/n? Thanks man

Thanks Steve! Perfect!...Oops just realized you said for install...what brand did you go with?

[Smolck]

I will get some better videos soon, I promise.

I went ebay style headers (might be bimmerbrakes original versions, not sure, bought them used) and all I replaced is the exhaust manifold studs, nuts and gaskets. That was all. I have really enjoyed the sound, but will be switching mufflers soon as the rasp is getting on my nerves now that window down weather is upon us. Trying to work out a deal with a friend who has an AC Schnitzer muffler off his old E46 laying around.

Under wide open throttle it sounds fine, really good actually. With the windows up, it is fine. But it is quite raspy when revving it and under 3/4 throttle.

Also what's the best and easiest way to get rid of the rasp in exhaust? Mufflers, new exhaust?

Resonator, specifically, anti-rasp.

[QC_ZHP]

Thanks Steve! Perfect!...Oops just realized you said for install...what brand did you go with?

I picked up a used set of Bimmerbrakes, version 2 I think? Not sure. $220 shipped and it came with wrap and a new O2 sim. I went w/ a used set over ebay hoping for a better fitment, but we'll see how it goes. I'll get them on soon.

None personally. They have different styles tailored for your tastes. Most are weld-in, so it doesn't really matter who makes it so long as you have someone to install it.

[Pip]

Just search ar20. It is the most commonly used resonator on the e46 m3 to remove the rasp.

[UdubBadger]

Ar 20 or ar 25 I think there is a difference in pipe size

Nice, aside from limiting rasp, what else do they do to the sound?

I don't know anyone who makes them. I made mine from some aluminum plate I had laying around. Steel might be better.

As for rasp, I say use a different muffler. I do not hear near the rasp with Borla or Magnaflow on youtube clips. I am waiting for my buddy to give a me a killer deal on his Schnitzer muffler. Below are a few clips of it on his regular 330ci. Had one resonator deleted and dual pipes all the way back from bimmer brakes headers. No rasp, I drove the car and it was great. On the last video, forward to 1:05 and you will hear my commentary :)

Those vids sound great though. Might need to keep an eye out for mufflers. I love Borla and used their systems on all of my mustangs, but I think its going to be a little louder than what I'm looking for on the e46.

It blocks off the SAP (Secondary Air Pump) which becomes useless after headers are installed.

Yea you may be right. Of course my car still has both resonators too though.

I have decided to keep the stock muffler and buy some AR25 resonators. Not sure where to add them at the moment, but I am thinking headers, deleted stock res #1 (cause it is heavy) and then AR25 resonators and then stock 2nd resonator then muffler. Or should I remove BOTH stock resonators? Confused. Anyone?

The AR25 videos on youtube, while all M3 cars, sound amazing. And since my car is about as raspy as a stock M3, this should sound close right? The loudness isn't my problem. It just doesn't sound "tight" and "clean" like it should. Looks like those AR25s do just exactly that. And I found them for $39 on ebay. And my friend has a welder.

That was a HUGE help. How did you find this? I looked through 30 videos or more trying to find a non M E46 with them and found nothing.

Think I may start with replacing second resonator like this guy did. If I dont like it, the first one is easy enough to hack off. And I don't mind being a guinea pig.

[QC_ZHP]

Just a little bit of googling. Not finding much else though, a few "can I put these on my car" threads but nothing more.

I'm having the same difficulties with choosing the right setup. There are some many different variables that come into play when messing with the sound of the exhaust an it's overwhelming. Resonators, headers, mufflers, and new exhaust systems could all be changed to find that perfect sound right? Does anyone have a prime setup that they use or used that sound great and would like to share? I wish they had an app where you could customize your own exhaust system and you could hear it! ��

[TigerTater]

This is great...! We all know what we want..deep, clean revs without rasp. Do ya'll know the difference in the bimmerbrakes V1 headers and the gen 3? The V1's are going for 275$ right now and im more apt to buying those than something off of eBay if I can help it.

[SoDelBMW]

I just looked at them and it just looks like the gen 3s are just a different design that maximizes performance and the v1s are just the cheaper design. There probably isn't much different but the rasp needs to go! We need to come up the best setup for a deep clean sound!

How do you intend to deal with the M3 muffler? Requires a diffuser modification, spare tire compartment removal (cutting it out and welding it up) and hanger mods. I'm curious as I've always wanted quad tips in the center

Also, I know a lot of folks say the 3" single exhaust is better, but does anyone have a quantifiable number? Does it add 5hp? 10? What?

There are ways to get the tips into the center, but if you want the M3 box style exhaust, yeah... That's what we're gonna do.

Yes, but those prices aren't right. It says right at the top of the page "Price only in combination with our insidePerformance M3-CSL-Look exhaust system!"

So eve pan if you could get it for 270 euros ($376) you'd still have to pay international shipping which will be $150 at least. Not worth it for $500 and the reality is, you'll probably pay closer to 700 just to get it here.
