I just purchased a set, black with the 3.5'' slip ons. They do included brackets that push the right rider floorboard a 1/2'' out to clear the exhaust. I didnt see anything about the passenger pegs in the instructions.
I will update you as soon as i get the exhaust installed
BTW J&P has an install vid if that will help you, its on a road glide, so i dont know how different it might be. https://www.youtube.com/watch?v=DmWALJFeIfY
Everything i read about the 3.5" vs 4" said the 3.5" was louder, Revzilla had it in a package deal also vs others like J&P had everything purchased in pieces.
Here is a photo of the whole system installed in black. I guess i didnt notice how they might or might not affect passenger pegs.
These are loud, but no obnoxious IMO, i love the sound more angry sounding than bass-y. I can record an exhaust clip if you are interested.
Hey Busch, I made you a cheesy little Video so you can hear the exhaust, I also used an iPhone decibel meter app so you can see how loud it is at idle.
The bike was cold, about 37 or so, so it could quiet after warm up.
I would have given you a few blips of the throttle, but it will shake the windows in my garage, and wake the neighborhood. lol
