Well i will be starting a project on my YZ450F and want to get quiet a few things for it. First i will be getting my suspension revalved and possibly getting stiffer shock and springs. Then i will be getting exhaust, lower gearing and bunch of small things such as radiator hoses, clutchcover, possibly stabialzer and new set of triple clamps, powdercoating the hubs and the swingarm black and other little things. My question is which Exhaust system would you recommend for the bike. I was thinking either FMF Powercore w/megabomb header or White Brothers Aluminum Pro or Carbon Fiber Pro. I was also thinking of getting HotCams, but was wondering if they make much difference and improve overall bike performance. What are some of the other things you would recommend to improve bikes handling and engine performance? Im open to any ideas.
