I was wondering if anyone could tell me if there is any possible way of keeping the stock muffler look but making it sound much more louder? any websites? Or does the 2006 600 rr sound evil right outa the showroom?

 

Hey welcome to the forum, the best way to get a louder and better sounding bike is to buy an aftermarket exhaust. IF you don't like the look of some Micron offers one that is identical to stock (it's louder than stock but quieter than most aftermarket pipes). Or you can punch or drill holes in the baffles of the stock exhaust(for instructions on this go to 600rr.net and do a search).

Hope this helps.
