Pricy for what it is, but works well and fairly easy to install

Used it on fmf 4.1 worked great

Bought this for my 450fx. Wasn't trying to get anymore power out of motor just change the curve a little and get a nicer note and spark arrestor. Removed a little hit off of the bottom but made the middle and top pull harder exactly what I was looking for. Install was a breeze. Exhaust note wasnt too loud. I would say very close to my dad's wr450 with the fmf q4 on it. Very happy

bought this to use for adjusting the air/fuel mixture on cv carbs, that i think it says it is made for but the shaft was too big to fit into the hole. on the bright side, it worked very well as part of my homemade valve adjusting tool for the kaw concours 1000

Put this on my bike along with the Dr. D radiator lowering kit and the two together made my bike handling a lot better than it ever did before. Recommend both kits for anyone with a 10-13 yz450
