2 1/2 downpipe to 3in catback.

[Flybiyou]

I have a guy that will sell me a 2 1/2 downpipe and 3"catback with 3" testpipt for 300.00 Only thing is will the downpipe be big enough for my future plans of 300whp. Will it also help so I dont boost creep. I read having a full 3" exhaust will make you boost creep in the higher rpms.

and do more searches? this question should be answered 100 times... But anyways for 300 WHP it shouldnt be a problem from what I read... Until actually I think someone said 400-450 whp it shouldnt be a problem...

Better safe than sorry though... but if you can get it for a good deal then do it.
