I bought a new WR450. It sounds like my neighbor's son's XR80. I see I have several exhaust options from a system, to a can, to a Pro Moto Billet performance baffle. I'm not Chad Reed. I do not think I will notice a half horse power difference between exhaust options. I will not notice the difference in ounces that a titanium pipe will make. I can hit the bathroom and loose that much weight before I go ride. With this in mind, is it worth spending the comparatively big dollars for a system or should I just buy the can. Or, will the Pro Moto Billet performance baffle make the bike sound correct and contribute sufficiently to the horesepower at a fraction of the cost. I am a comparatively hard core Vet rider who rides primarily Northern California single track.
