Someone prove to me that just bolting on this exhaust will add 16hp to my WR and I will buy you the latest Ti muffler bearings and give you first shot on the swamp land I have for sale.

It may be a little exagerated but the concept of adjusting the noise level is pretty cool. I would like to get any feedback from anyone that may have dealt with this company and their products. Time to research the web.

I work at a Yamaha shop and have ridden both the WR 250 and WR 450-Stock out of the crate they only run half as good as a YZF so I think the numbers are true.
