So I have been researching my exhaust options for the 75b. While I really love the way the peashooter mufflers look, the reviews on the sound is less than appealing. I am sure I will be happy with the Commando exhaust that Mike's sells, as everyone seems to like them. I have watched videos and read posts until I went cross-eyed. My stock head pipes are in very good condition so I could easily just buy the mufflers and mount them up. My main question is, how much difference in sound would there be from running the stock double wall pipes versus the Mikes single wall 1.5" head pipes. I am wanting a bit deeper tone but wonder if the extra $170 for the bigger head pipes will really be noticeable. Is there any real advantage in running the full exhaust over just the slip on mufflers?
