New, used? Miles?

I see it has the pre and post cat O2 sensor bungs, but no cats. How does that work?

Thanks

They are used and with only 15,000 miles on them. I'm sorry to have forgotten to mention that.

That's a good question, I believe it is so you can attempt to run non-foulers. I've had friends run non-foulers with good luck.... and I've had others run them with no success. Non-foulers should work if to space them properly.

Good seller, folks.

So....non-foulers give the car a simulated CAT reading?

Essentially... By spacing out the O2 sensors, the sensor doesn't have as much flow of exhaust fumes over it.

MS43 folks have it easy... They can flash their DME with EU2 and do away with post cat sensors and SAP. I've done it for my friends with MS43.
