I would like to do Bob G's set up. I like the fact that I have no resonance with Corsa..

With the Z06 NPP valves, you get the low resonance of a Corsa w resonator but w 3" pipe. If you look at the stock Z06 exhaust, it has an X pipe but no resonator. Not needed. So weight savings and less restrictions. Pretty quiet at cruise. But then it opens at WOT.
My setup has no resonator, just SW XPipe, DynoMax UltraFlo, 3" pipe w Watson headers.
