I recenlty installed a jet kit on my bike but I was told that I need to put on a different muffler but I have not found one that I like or is not so loud. Is there a way that I can keep the stock muffler. Also I was told that I have to change the air filter. And I was going to get a K& N Filter but also I was told and read that those let too much dirt through. Is this true and can I keep my stock muffler and do something else to let more air flow in. Please help as my bike is not running yet and I want to ride. Thank you very much
