If you ride one of these Yamaha Shadows...(I think that's what it is called) I am going to make a one time offer. Bring me your bike for a head back exhaust at 50% off. That's right, to save you embarrassment from riding around on a muffler with wheels. Seriously, this thing looks like an oriental rug rolled up and stuffed onto the end of a couple pipes. So, For $500 do yourself a favor and save your image.
