So I have a Ram 2500 with the 488 V10. Now Im looking to put a flowmaster on the truck but want recommendations with which one to go with. I want it to sound good but dont want it to be annoyingly loud. I was considering the 50 series. And yes I know with the V10 it will sound off when compared to how a V8 sounds but still want to do it anyway, the other question I have is does anyone know what to do with the air tubes that run into the cats if I were to say cut my cats off, Ive heard of some guys running them back into the exhaust pipe it self but heard that may cause back firing issues, so anyone know of any better ways to handle that? Thanks in advance.
