For you a can only cost $225 because you only bought a can. He can't though, the 500 engine has a one piece pipe and can, he'll have to buy a new pipe and can. To the best of my knowledge no-one makes a pipe and can that makes good power gain on the 500, so it would be $600 (approx) for more noise and maybe some weight loss.farmer_mike said:Go for the can, I just put an mbrp race on mine and the awesome sound was well worth the $225, some people will say you will lose hp, but I didn't notice any loss (a dyno might say I lost a couple hp though). I did notice the loss in weight which was a welcome bonus.
P.S. Before any of you naysayers start getting on my case I don't ride any groomed trails!
