My question is similar to Burns' post of earlier today.

I've got an 07 Ultra with stock exhaust and I'm in the process of making some changes to increase its performance. Not sure what to do about exhaust. I want to improve the exhaust performance but I don't want what for me is an offensively loud exhaust. I realize there is a trade off here and I'm interested in the forum's opinions of how to get the most performance with the least increase in sound volume. Thanks.

 

Supertrapp. You can adjust the sound level by adding or removing discs, and it probably makes as much power as anything else.

 

The super trap supermeg is raved about by one builder. Forget if it is quarter something, quarter....... Dam. Anyways, he gets the best performance on his builds with the supermeg. Headquarters, that's the guy.
