Thanks to all who responded to my earlier post about SE Street Perf mufflers. After hearing a set and further research, I'm not considering them. One HD dealer I went to refuses to even carry them saying they're no better than stock. The sound I'm looking for is the classic deep bass Harley rumble, not sheer volume. After reading about (thanks flstcdorr!) and hearing a set of Rush mufflers, I'm pretty sure I'm going to go with them. They were on a 103" Road King and had 1.75 baffles. They were a little too loud for my taste but the service manager said they are louder on a 103" touring bike than they would be on a 96" Heritage. Also, it was indoors in the echoey service garage. I've read nothing but praise about the sound and performance of Rush. The question now is should I go with the 2.0 or 1.75 baffles? Again, the deeper tone the better, not ear-splitting loud. I'd like to hear from others who have the Rush slip ons. If you want the sound I want, are you happy with them and what size baffles do you have? C'mon spring. Gotta ride!
