i ran a 2.5" Flowmaster setup all last year with the Procharger/6.0, but now i have the stroker, AFR 225 heads, EPP cam, wonder if a switch to 3" would yield much-its in an A body, true dual exhaust
not sure what size the Vette/Camaro guys are running

Did you change the pulleys on the procharger? If not then you'll be making less boost with the new setup and close to the same power levels as before. If you're pullying up then definitely go bigger on the exhaust. What power were you putting down? Which procharger?

It will help yes, also the flowdisaters are making matters worse. Should make great power with the new setup.

Definitely do a 3" or even 3.5" with a bullet (straight through) type muffler and no cat if possible. I'm running 3.5" duals with my procharger setup
