I wish I could directly address your question, but I cant. I have an 05 & the Supertrapp wouldnt go on far enough to allow both bolts on the rear support to engage. I shortened the header with a grinder, much drama, when battery fumes & sprks from grinder met.Fumes exploded, battery case cracked & crap flew( NOT literally, but close!
) If the question is, will a Supertrapp go on your bike? The answer is yes, Some here have managed to make the Trapp go aLL the way on, no hassle. Others accepted just having one bolt on the rear support. I have seen no one report they regretted that choice, I am just kinda anal about that kina stuff & wanted Both in it, so I went the way some others have gone, took a grinder & hogged it off. There is more than one way to skin this cat. The Supertrapp is a cool muffler, sounds good,not crazy loud & is tuneable. It is also quite a lot lighter than stock, but then so are some smaller boat anchors.
