What mufflers?

I'm running a pair of Pype's Race Pros (and X-pipe) which is a straight through design like the Dyno UltraFlo. Not bad. The Pypes Violator is way too loud and ratty for my taste. Both have quite a bark when you get on it. I might try the Dyno Super Turbo if it has a little deeper tone - which I presume it does.
