Put some Rush slip-ons, on the bike this weekend. Was easy to do and sound great. I used the 2 inch baffles, much louder then stock but not annoyingly loud. I used mufflers for an HD Dyna, fit great and fairly inexpensive. Didn't notice much HP or TQ increase but did lighten the rear up by roughly 10lbs. Rode over 100 miles, didn't go def and bike handled great.
