I have been lokking into customizing my new ride. I think that the first thing i should upgrade is the cat-back. I am a Rotary Guy from the age 15 and i know that with the N/A compared to the Turbo version the cat-back is the same. Is this true with the B5 A4's?

 

no a 1.8t engine and a 2.8 have different exhaust, one is a v6 the other a 4 cylinder

 

I know that. But i was thinking that maybe just the cat-back was the same or followed the same lines under the car.

 

well the cat on the 1.8 is only a few inches from teh turbo but they probably follow the same path later on down the car but i dont know for sure

 

While we're on the topic I am thinking about taking my cat out beside the fact that the CEL light would come on because of the O2 censors what could go wrong. Here in Ohio we don't have emmissons standards.

 

What part of ohio are you from, im in columbus-(dublin)

 

I lived in columbus for 5 years i went to OSU, but now i am in cincinnati

 

if you dont mind the cel light staring you in the face, and everybody asking about it, then there's no problem...

 

completely different, in the 1.8t you have (in this order) turbo, cat, downpipe. the cat bolts right to the turbo. theres your answer.

 

Thank you.
