So as the title somewhat states...we don't have emissions where I live. I run a 2.25' straight pipe on my prelude and would like to get the max out of my audi.

So do i essentially need a CAT for the car to run properly? I know theres another o2 sensor up in there but can i just relocate it?

What is a good alternative as far as test pipes & **** go?

Thanks guys

I run a e code test pipe and it is so nice, much more power and the sound is pretty good as well, the O2 sensors go right in the test pipe but you need to space the rear one out so i wont throw a cel

 

sweeet! thanks buddy
