I will be getting a JRSC in the future and I wanted to know what is a good exhaust diameter to have???? I'm asking this because I might be getting a deal on a used DC Sports catback. Would that exhaust flow enough?? Thanks guys

 

what boost level do you plan on? i've heard anywhere from 2 1/2 to 3 being effective.

 

I would just be running 6psi

 

Would 2.25" be enough??

 

i'm going to find out this spring i'll have the same setup. but, until then, maybe search around on here and i guarantee you you'll find tons of matches: http://www.hostboard.com/cgi-bin/ult...bb=forum&f=110
