I ran open for a few months during shake down...scared some people at a bus stop (1st gear), that was about the only enjoyment it brought me.

quite the sleeper with a stock main cat, RB duals, and open WG, LOL!! I've now got a hi flow small ceramic cat and resonator in the mid-pipe, flows quite a bit better.

The only thing stopping from trying it right now is the fact that I am currectly unemployed.

With my MP or my small hi-flow cat, there is room besides it to fit a small muffler from a mini bike or ATV. You do not need to make it quite, just not louder than your normal exhaust.

Do a web serach for ATV or small motorcycle mufflers.
