I assume you don't like it.
Does it kill the power?

I have one and love it, a lot less restrictive than like the GTR replacement. The only thing negitive I can say about is all the holes they drilled into the end of it for I guess looks, kinda gets full of dirt and mud.

I'll take it if Kentucky doesn't want it. I can't help but wonder if this thing might be just a bit noisy.

Let me know.

I liked it but for my jetting the GYTR workes better. I have kept it and was thinking about drilling out all the holes to give more air flow but never really got around to it.

Ryan, it works as advertised. It tested at 94db at an enduro I entered. The end cap is almost identical to that of a TTR250 baffle.

I picked up a YZ 450 pipe off e-bay for $80. I put a Pro Moto Billet end cap on it with the optional Spark arrestor and there is a silence insert you can get as well. I am not sure about the WR version but I am very happy with what results I received for the yz pipe. It was pretty easy to install. I think it beats the FMF Q because it's adjustable to what kind of riding you are doing. I must have saved at least 2 1/2 pounds!

Did the same thing on my 426, man what a difference from the stock WR exhaust. :)

Just set up the wr400 with a yz pipe,pro moto billet spark arrestor and silent insert. I have a fmf oversize head pipe and power now intake. The results are a slight loss of power in the midrange and up. Sound is quite a bit less. All in all I think its a good deal and the set up for a stock yz pipe if you need sparkarrestor/less noise. Also a very high quality item too. Note: I kept stock jetting, had to adjust mixture slightly. :)
