Hello, im looking to purchase a testpipe for my 02 i4 coupe and i cant seem to find any online stores that carry them. Mufflertech.com and testpipe.com only have hi flow cats and mufflers, exhaust, etc but no testpipe. Can anyone tell me where i can find one? Thanks.

 

I got mine on Ebay.

 

Make your own. It's not hard. However, you'll have CEL city unless you find some way to disable that 2nd O2 sensor.

 

i heard there is a o2 simulator but i dont know how that works nor where to purchase that.

 

Ask niedejb about his. I'm pretty sure I saw on his site that he was using one.

 

He bypass it i believe..
he taught me how to bypass mine when i have my high flow cat on.

 

serious dont get caught with a test pipe in Cali..
big fat ticket

 

how do you bypass the o2 sensor?? any instructions or stuff like that?
