i have a ITR peakboost turbo kit, what exhaust from experince or word is best for a turbo setup on a R, 70-76mm.. i like all the exhausts cant choose, they all sound very nice, i like the burnt blue tip on the hks hipower and 5zigen pro exhausts, if i go with hks im gonna do kteller 3" piping also, 5zigen will be 70mm, and skunk2 will be 76mm, lemme kno what you guys would perfer, my car when finished will be around 350whp

 

with boost bigger is always better, but if your only shooting for 350whp, get which ever one you think looks and sounds the best, at that level there all going to perform the same

 

3" thermal cat back

 

No exhaust would be the best option...BUT if you want something quiet, I would go with 3" piping to a maganflow muffler (This is what I used)

 

T1R 70R.

They are kind of hard to find, but the next best would be the Skunk2 70mm.

 

if i could find a t1r it would already be bought
