Ok so I was up at my local stealership picking up some oil and a filter and wound up talking to a guy in the service department that races a 450r. I asked him what he thought of the HRC kit and he said that I would be better off, money wise, by buying a jet kit, a cam, and a slip on pipe. I got quoted $290 +tax for the kit and $150 for the labor to have the full HRC kit put on my R. As far as i can tell that is gonna be the cheaper option. The other thing i am thinking is that the HRC comes with a full header so that is gonna be better than just a slip on right? What do yall think?
