ok, i am running a star stage 2 and i just purchased a Greddy EVo2 catback. The exhaust shop told me that i needed a 3-bolt flange for the downpipe so it will mate with the exhaust and also a 2-bolt for the end of the 3in high-flow cat. anybody know where i would find these flanges? i tried Roadrace engineering and didn't see what i needed. what sizes would these be? like 2.5in? if so how would this mate with the 3in exhaust?? i searched and couldnt find an answer. thanks for all your help.

If the greddy exhaust if for your application, there shouldnt be a 3 bolt flange, just 2 to go into the downpipe or cat.

well its the greddy evo2 for the GST, but it should fit?? i got that oned b/c it is the 3inch style.
