Funny enough… I was revisiting that when I was putting back on my tusk racks. It’s the bracket that you add with the tusk Pannier racks that the clearance issue. Without that bracket, I think you should be OK.
Thank you for posting this John, just received the same pipe. It takes me 10x longer to install things, so very much appreciate the breakdown. Curious what muffler you put on? Thanks again @ripnriding1
