what size exhaust ?

[MR.LANCER]

got an evo 6 come in which is all standard yet.

upgrading the exhaust from the cat up to rear box.

going for a 3inch all the way straight with a centre box, is that the best size or would i be better at 2.5inch for max power gains ?

i have been confused by another member lol

3" will be good but a 2.5" may just have better performance. It all depends on the overall package that will determine the best size.
