turbo, I vote 3". There is a lot of talk of that on here.

b6 don't go past 2, v6 N/A was 2.5, and any turbo application was at 3".

At least I think that was a general consensus.

I agree

if you want reasons why, do a search it has been argued/debated many times!

Win!

I would just do a 3" .
though that also depends on what size exhaust side you run on the turbo and what turbo you use.

def. stick w/ a 2.5" exhaust and you'll be fine unless you plan on putting down 350ish hp (which is quite a bit if you're using it as a daily driver on a FWD car)

Side exhaust would be cool though :) You should just go w/ no exhaust and have it end after the downpipes/turbo! It'd sound bada55!

What i meant by exhaust side of the turbo is the a/r of the exhaust side.
As in if you were using a .48,.63,.82 etc etc..
say if you were using a .48 a 3 inch exhaust would leave little benefit for you, since your biggest restriction would be the exhaust housing itself.
vs the .63, .82 where i would almost say the 3" is required to make the most power.
