what exhaust for my turbo ej8??

[silverbullet]

hey guys, i recently turbo'd my ej8 and was thinking of upgrading the exhaust.. what size would be best, i have access to a skunk2 2.75 inch full system.. will that be big enough, thanks...

yes yes yes lol, depends how much power ur aiming for as well, generally 3 inch is good for 400hp or more, minimum id go is 60mm, than after that 80mm if going for a prefabbed exhaust, if going custom go 2.5 or as u mentioned

I agree with mugen_ctr.

60mm minimum. 2.75" could be fine. My friend runs 3" on his B16A turbo and is making just shy of 200kw ATW.

So probably 60mm min to 2.75" max

How much power are you hoping to make?

yes would be fine.
i'm currently running a 2.5 inch cat back exhaust with a 3inch dump.
using a garret gt2871r and 17psi making 248kw atw.
obviously running a 3inch will yield more power, though, more power is not needed and it is more quieter.
