well... I've decided to ditch the sweptside setup and go for flowmaster40 duals (s/i d/o) and I was wondering what size is best for the piping?

I was reading somewhere the 2 1/2 in and 2 1/4 out is the best to keep torque #'s

WHAT WAS THE FINAL VERDICT?? haha

I did so much searching I can't take it..

c'mon guys.. someone here has to know

 

I can't answer your question, but rather I have a question instead. Are you getting rid of the ravin muffler simply to go to a SI/DO setup? Did you like the ravin sound? I may be interested in the muffler if you planning on selling it. My e-mail is dbutcher@watlow.com. Let me know.

 

I am going for a Flowmastr40 si/do.. but the Ravin sounds rules.. it is awesome for a 6..

I am just bored and want a diffrent setup

I will email ya
