Exhaust Size for Turbo

[LsVtecStolen]

What is the proper piping size for a turbo application? 3 inch, 2 1/2?..

I know you can get away with using your stock exhaust, but you won't feel the "full potential" of the turbo.

I have an exhaust with 2.3 catback piping. Should I just sell it and get a custom 3 inch catback exhaust?

Thanks for the help..

the bigger the better, infact, ive got a dump on my gn that u run 24/7.

the larger the pipe, the more exhaust sound you will get. on a turbo car get as loud as you can stand it, that is my best suggestion. bigger=louder=faster on a turbo car.:D
