Do you guys think a comptech exhaust with the resonator removed and the "y" moved up to the cat it would flow enough for low to mid 400 at the wheels? just curious since we have the exhaust here and cant find a dual that looks good..... so basicly dual 2" from the cat back

 

s2kkyo ran the comptech exhaust with his inlinepro setup

 

The more wide open the exhaust the more power gains you will see. you can run any exhaust with a turbo. there was a guy making 500 plus on a stock exhaust. the bad thing about running a small exhaust is that it will cause back pressure which will wear your turbo out quicker. so in my opion I would not go any smaller than a 70mm exhaust. just my two cents.
