2.5 Test pipe with 3" cat back
Hi, I was recently debating on getting a 3" testpipe because of the cost but I just noticed that the bursch test pipe is pretty cheap but only 2.5". I was wonder if this would still increase performance even though its still 2.5". Also anyone know where I can get one?

Not sure about the 2.5" vs the 3" but either one would reduce the back pressure (no CAT) and bring spool up time down and increase boost a bit.

Do a search man, I asked the same question about 6 months ago. The answer was that the 3" is not worth it unless you have a lot of power upgrades. Just want to let you know. There where a lot of people that responded to that thread.
