What mm test pipe for stock exhaust for 02 ap1 63mm? cars got borla mufflers megan header

 

Want it to match exhaust size. So 60-63mm will be what you want.

 

OEM exhaust is 60mm, get the 60mm TP.

 

Yea I was reading a thread home boy did with all the dyno's and it looked like size matching was of high importance So just wanted to double check... I also hear tp brand don't matter...But I'm thinking T1R OR INVIDA?

 

ive had problems with invidia's tp cel fix. i would go with berk

 

If I remember correctly Berk doesnt make a 60mm TP, only 63mm & 70mm. I have the 60mm Invidia w/ CEL fix and I havent had any problems. Just get the Invidia and if for some reason you still get a CEL just get some anti foulers and that will solve the problem.

 

I got a Invidia tp with T1R cel fix from a forum member thanks.

 

Better yet, get a 3" cat-back and then get a 3" test-pipe
