Super quiet at low rpms starts to resonate towards 2.5~3k.

this is my second one of these. great build quality, can get a little drony if installed with no resonator on a 3.00" or larger pipe. and the stainless 409 version comes coated in something - not sure if ceramic paint or just high temp paint, but it looks MUCH better polished. great quality.
