So I pulled the trigger on a pair of Flowmaster 40s for my npp system. Startup is amazing and it shakes the ground, as a muscle car should. Drone is a bit annoying at lower rpms at low speed but almost zero on the highway. My only complaint is that at higher rpms the exhaust is quite a bit quieter than the npp
. Anyone know of a different muffler that I could swap in that would give me that scream that the npp has at the top end?
