You could try switching to those new mufflers with sound/pressure valves. Wide open they flow like straight pipes, the rest of the time they mello out and eliminate drone. Dynomax VT's, otherwise you'll need to upgrade more of the exhaust system to produce the tone your looking for, or ditch the mufflers all together, but then you'll have much more drone. Just a newish option for those who don't want to change the whole exhaust, want straight pipe sound at wide open, and want to hear themselves think while cruising on the highway.
