Sorry, no reply here, but is someone going to Ban Mr. Belts in the above post?

 

I dont know much about your personal setup but if your closer to stock than not your going to be hurting yourself. By taking it to 3 in. you eliminating alot of essential backpressure and going to create more lag from the turbo.

 

ESSENTIAL BACKPRESSURE??????????????

why do u think boosted cars go big w/ exhaust diameter? You only want back pressure before the turbo, not after. the only thing a larger diameter hurts on a boosted car is your pocket.
you only want backpressure on a n/a car.

 

i agree, the wider the better!!!
