bang for the buck its the best way to go
i inherited a brand new with about 20hrs on it only honda 5000 it came with a muffler and its no louder then a sport bike at idle. i was just making suggestions just in case you decided to go the alternate way. i have seen a couple guys with mini bike mufflers and they are pretty quiet!
