macx Posted May 22, 2011 Share Posted May 22, 2011 I'd looked into these for my R1150R, even heard a sound bite with one on an old airhead (sorry, can't find it now) but it sounded really nice - powerful and mellow, no harsh rap. That was with the end cap on. With the end cap removed, it sounded like an old Cherry Bomb glasspack, lots of harshness and rapping. Just realized one of these might make a comparatively cost effective muffler swap for the 1200RT's and make it sound much better. http://www.supertrapp.com/product_sections/cat.asp?CatID=30 I haven't actually measured the stock muffler, but the 3-1/2" dia by 17" or 24" body length might work and get the exhaust out behind the system case and far enuf away from the tire, and maybe even with the stock muffler mounting band. They've got a slash cut end that could be positioned so the longest part is toward the tire to keep exhaust from blowing on and heating the tire and blackening the rim. Otherwise, there's the 4-1/2" dia by 19" length unit that might fit the stock mount clamp, but it's a 2-1/2" inlet that would have to be adapted down to the pipe coming out of the cat which, in any event, would have to be cut off pretty close to the stock muffler so the SuperTrapp would slip over it after it straightens out. BTW - when I looked at mine, I saw what I think is the "exhaust flap" - anybody know if that can be made to stay open without messing up the electronic engine controls, and what it might sound like under normal driving with the thing open, disconnected, or whatever, with the stock muffler?
