I ordered my new exhaust today..I ordered the RS*R gt-2 exhaust ...now my question is will it bolt up to the 2.5 outlet on my test pipe...or is this exhAaust more like a slip fit where you just slip it on to the collector and clamp it????

 

I'm not sure if this is the answer you want but I guess I'll go ahead. All the exhausts I have ever seen for these caRs have flanges that will bolt up to your cat or test pipe.

The question is will the test pipe or cat be too long or short to fit with the exhaust and the header?

 

I replaced my cat. w/ a testpipe because the header io have has a 2.5 outlet and the stock cat. couldnt support that so i just had a custom2.5 flange kit welded on the two and a half test pipe

 

Yea, most exhausts come with a flange on the end. 2.5 is a good number so maybe you will get lucky.

 

HOpefully thanks anyways...apreciate uit much
