So I did the mod last night, took 2 minutes max. The one thing I did notice was the deeper tones at the low RPMs... but there *almost* seems to be a little drone when you're cruising on the freeway. Not exactly a bad thing, but I can definitely hear the exhaust when I'm even slightly on the gas going 65. Anyone else notice that?
