Reply to "Seeking feedback regarding new mufflers and their effect on EXHAUST DRONE"

Hi Dick, my '72 has a massive resonance around 1800 rpm but it fades quicker than your situation....maybe by 2000 rpm it's mostly gone. In that small range, however, the rumble must be rattling all the neighbor's windows....I'm sure they appreciate that lots! I don't remember where the mufflers were from but they are stock upswept (i.e., early type) Ansas. The resonance was there from new, I always assumed it was normal with some of these systems.
