downpipe question?
 

my turbo is a t28... t25 with t3 echaust housing? the outlet on the exhaust is 3in should i just make a 3 in dp, or reduce down. im going to be buying a t3 .60 trim but that is later on down the road.

Re:downpipe question?
 

2.5 or 3.0in pipe is more than enough. There's not to much of a diff between a 2.5 and 3.0 when running anything less than 12psi or under 300whp.

Umm i dont have much to say buy i would choose 2 3\4in cause beyond that is just a waste. 3in is too big unless your boosting 15psi+... bigger is not always better!
