I have a Morgan-Tec Stainless Steel with Monza Big Bore (2 1/4) Resonator Exhaust tips and the combo sounds Great. Before I installed the tips it was alittle loud under a load(up hills. etc) and a certain RPM's, but once I installed the Resonator tips it sounds great, A nice Throaty sound.
And the workmanship is Great on the Muffler.......
