I tried several mufflers and they all had that annoying resonance. One I found that gives a higher-flow rate without the resonance is the Dansk sport muffler. It looks like our OEM mufflers, but with different internals and higher flow rate, at least that is what the folks at Dansk said.

I did a before and after dyno with the stock muffler and the Dansk, it was really too close to call. The dyno said I picked up 2-3 hp, which, although probably within the range of error of the Dynojet dyno, speaks to a little better flow rate with the Dansk.
