2003 BMW F650CS Exhaust swap. This bike came with the Dominator aftermarket exhaust when I purchased it. It was a bit too loud for my taste and a little annoying while driving through the neighborhood. Unfortunately it did not come with the stock muffler so I picked one up on Ebay. I do like the stock sound better but I will hang on to the Dominator pipe as it's an easy swap and might be fun to use up in the mountains. I did notice a lot less exhaust pop with the stock muffler. I don't really notice any power difference between the two. Hopefully this video will help someone who is deciding if they want an aftermarket exhaust or not.
