I bought a 2007 honda shadow sabre 1100c2 trike...3 wheels. Its run loud. I would like to quiet it down because of the condo complex I live in. Several friends told me to buy a slip on muffler and that should take care of the noise. Anyone tried this before? The pipes run under the trike and are several inches from the edge of the back of the trike. I guess it isn;t good to have any of the pipes sticking out of the rear end? Thanks
