People seem to have installed complete exhaust systems as they are available. If you have can you tell me if as it looks, the stock muffler attaches to the exhaust with a clamp. I may be wrong, but it the muffler is removable I can wait for a slip on to become available. Then if I need warranty service I can just re install the original muffler. Most bikes I've owned didn't need a complete system for better sound and a small performance gain and weight loss.
