To the 450r owners out there that have an aftermarket exhaust, what is a good pipe that adds power and isnt overly loud with a good price llike 500 and below. How much power does it add off stock with an hrc kit installed??? ALso is it worth the money?
thanks

 

I have the HRC cam. EHS Racing airbox lid, with Outerwears cover. FMF Factory 4 exhaust. With the quietcore, it isn't overly loud. The bike can go faster than I ever care to go!
