Magnaflow Headers

[Aeternalis]

Apparently Magnaflow makes catted "headers" for our cars.

I found these pictures on bimmerforums. They aren't the prettiest but they look a hell of a lot nicer than the stock pieces, surprisingly. They're pricy, too, at around $500/ea ($1000 for both fore and aft sections; $830/$1660 for CARB/NY versions) but they look like they would flow much better than stock while also retaining the catalytic converters. Less headache dealing with rasp and coding necessities with catless headers too.

I might go this route and get them ceramic coated instead of getting the bimmerbrakes headers.

What are your thoughts?

I came across those prior to starting my OEM M3 header conversion project... I could never find them for sale or any indication that they are still in production.. when you go to magnaflow's website, the product depicted is another cast manifold, very similar to stock.

Based on my recent experience with the M3 conversion, if they did make them tubular, like the pic on the link, then ~$1000 isn't a bad deal.

If/when I do decided to pull the trigger on these, I'll be sure to post tons of pictures. Worst case scenario--if they're no different from the stock design--I can just send them back to Amazon.

Rear: http://www.amazon.com/Magnaflow-50288-Direct-Catalytic-Converter/dp/B00861H756

The 3D models Amazon (and other sites like Jegs and Summit) uses as pictures seem to indicate tubular primaries contrary to what's on Magnaflow's website. Strange.

thanks.... those aren't being sold by amazon so not sure you could send them back?

they've got two versions, the california version and the non-california version. :) these look like the non-cali ones... exactly what i would get.

The independent seller has them listed for cheaper than Amazon proper:

25970

$682 seems to be the going "retailer" price. They're on Summit as well:

50287/50288 are indeed the "Federal" versions. The 4xxxx part numbers are the CARB ones.

Those are no longer made like that. Magnaflow changed back to the stock saucer design with these, so everyone regards them as simply OEM replacements now. And, those who had supercharged cars reported burning out the cats in these.

There's a thread over on e46f that's tracked the life of these

Sadness. :(

Just read through the E46F thread. I hope Vorshlag can come up with something good for our cars. They're local to me.. maybe I'll get in touch and see if I can be a test mule. :) Lol.

I know, that would be awesome. I haven't heard anything from them in a while though, go knock on their door and see what they say :)

Been interested in new headers but being in California is basically a no, you say your doing an oem m3 header conversion, would that still pass ca smog?
