bmwtye

Yes I still have mine.

I have stock headers/cats, side mufflers, titanium rear center muffler, titanium exhaust tips, plus a bunch of other stuff off the motor and trans of a 2011 RS with 5k miles. PM me if you still haven't found what you were looking for.

LateBraking

My turn to ask, I'm searching as well.

RedRSA

None available here, but I have a question: For the those who posted that they were looking for stock headers, what is the reason - is it becUs of a bad cat on your original? If so, that is an obvious problem with having the cats welded into the headers. I'm wondering how often it actually becomes a problem.

Thank you, and good luck.

Spyerx

well for those CA...
Passing smog if previous owner swapped headers and didn't keep originals
Bad cats
Dented header pipes

For me it's bad cats. I just bought my 997.1 GT3 a few days ago. Long story short, previous owner in good faith replaced a O2 sensor since that's what the dealer said was broken on the car. The CEL came back on after I took delivery of the vehicle, same exact code (P0430 both before and after I took delivery). I know I could "get a tune and catless headers" but I'm really not into modifying vehicles anymore so I just want stock cats and a CEL-free experience.

Spyerx

Yeah, P0430 & P0420 are cat efficiency errors. First step is to test the post cat o2 sensor, and if good it's probably the cat.

LateBraking

Yep! Tested and replaced with a brand new one, and still getting the O2 error. So I'm thinking it's probably the cat like you said.

MJSpeed

I have these M&M headers and they don't throw off any CEL lights whatsoever.

Just buy a new set for that side.

Or weld in a replacement.

LateBraking

Right! Don't need a set anymore. Long story short, it's getting replaced.

I'm curious though. My new-to-me car has under 30k miles and a cat went bad on it already. This is normal for GT3's? Never encountered this sort of issue before.

FJSeattle

Cats fail all the time. 30K miles is not bad for a premature failure.
