I have a '02 GMC reg.cab, s/b that I want to install a after cat dual exhaust. I have a flowmaster 70 series muffler w/ 3" single inlet and 2 1/2" and a pair of corvette style tips. Does this sound like a good setup? or should I go with a aftermarket exhaust. any suggestions would help.

 

It'd be pretty quiet and not gain too much power. If you need quiet and want a bit more power...Magnaflow has a HUGE 5x11x22 size muffler that flows great but keeps sound low.

Heck Dynomax SuperTurbo's are cheap and sound great. Little drone too.

 

super tubros are junk and are not worth the effort.
yes your truck will be fine. i have force II set up and i like mine.

 

I'd prefer that over this Flowmaster I have. I like the sounds, deep, mellow, low resonation, and cheap. To each their own...I just don't want the same setup as 90% of the people do.
