I think you'll find many different opinions on sound. are you looking for wake the dead loud, or on the other end of the spectrum just a bit more rumble. I have the SE torque slip on mufflers on my heritage and like them. I started with cycle shack full exhaust and it was too loud for my taste. many people go with vance and hines, good looking and sounding pipes. I'm sure you'll be asked if performance is an issue when choosing.
