I have owned a 400EX for a little over a year now and just bought a 450ES for hunting. In the past year I have done the typical mods to my EX(pipe, K&N, jetting, etc.) with great results. I would also like to increase the performance of my new 450ES as well. Has anyone performed these kind of mods with good results. Any suggestions on pipes or other mods. I'm also looking for a pipe that will increase performance without increasing the noise level since I will be using it for hunting.

 

White Brothers came out with a pipe for the 450. I believe it was the August issue of Dirt Wheels.

 

Go to Highlifter (www.highlifter.com), they have things like a bore kit, piston, and cam.

 

i would get the highlifter performance kit and the highlifter 475 big bore kit with a web cam
and i wouldnt get the white brothers pipe cause it is open disk the disks clog when you mud ride
