I like the sound of the stock muffler too. With earplugs, didn't even notice the engine running. With the TBR, always hear the droning of the exhaust tone, and listen for RPM tonal scale changes, and try to mate the tone to accompanying speed. Sounds weird, but as a life long musician, sounds have always fascinated me.
Currently watching Funny Lady, just for the music and Barbra's singing abilities. TMI? Probably so. tp
