Question: Why is it that we are still using loud glasspack mufflers when the automotive industry discarded them decades ago because they really dont flow all that well anyway? Surely, there has got to be a better way! I love my 450 but im almost embarrassed to ride it anywhere near people because it is so offensively loud, my neighbors must hate my guts but are too nice to say anything. We have a little neighborhood track here that a bunch of us ride, but mine is the only bike that is really painful to listen to. Im worried about it but I still havent found a solution. Any ideas? FWIW im running the stock exhaust with a PMB quiet insert that kills power and isnt that quiet, I had high hopes for it but the 450 is just too much for it.
