Check out the baffled mufflers from WitchDoctors..
There are multiple clips on Youtube, the one where Jon was at Daytona got me real interested. So I just put them on my XCT...stock was just way too 'polite' and I heard more noise from the engine that I did from the exhausts. But I love these new WD pipes...louder than a Victory Stage 1 at any speeed and throttle setting and it raps very nicely when rolling on the throttle...these are EXACTLY what I was looking for. No reflashing necessary, only thing I had dome earlier was to disconnect the 02 sensors which cured the popping and backfiring. VERY happy camper here with the WD pipes..
