I've been running mine for a year without the muffler (resonator still there) and am considering RIP's 4" exhaust with muffler. Anyone got this set-up and does it make it quieter than without stock muffler? Are you satisfied with EGT's. etc. ? If it's quieter than without stock, I might have to get it without muffler.
Any comments would be appreciated.
