Here are a couple of pictures of how I modified a set of rear muffler hangers for my 2005 Hayabusa for use with a Yoshimura Duplex TRS system. On the right side I shaved the passenger foot peg mount completely off the muffler hanger. I spent about 1/2 hour reshaping the metal with a grinder, files, orbital sander, finally finishing with hand-sanding. On the left side I had no need for footpeg or hander. Rather than leave a hole in the bodywork by taking the hanger completely off, I trimmed the hanger down and shaped it. The reshaped part fills the gap in the bodywork nicely. I painted the parts black rather than try to match the silver. I haven't seen anyone else have this mod, so I thought I would post it.
