custom exhaust

does any body have a custom exhaust for there 02 wrx? iam going to get one done for me, it will be three inches from the turbo back and i was wondering if that would through of the o2 sensors or if there would be any sort of problems with that. also if i do that will there be enough back presher for the engine?

 

You don't have to worry about backpressure, I think there is a o2 sensor fix you can buy so you don't get a CEL. What are you running that you need 3inch exhaust for?

 

iam planning on getting a biger turbo maybe a PE181 or something else

 

search on nasioc. there are many good brands. Just make sure its 3in all the way through, and has a bellmouth down pipe and you will be good.

 

I'll be running 3-in turbo back, even with this small snail...you want as little restrictions as possible on a turbo car, even if its stock

 

where do you buy an 02 sensor fixer so my check engine light dosent come on? does any body know

 

build it... there is a thread here or on nasioc to do it.. takes like 10mins and costs about $5

 

if you find that thread or know where it is can you let me know thanks, i cant seem to find it. must be not typing the right words.
