My bike is a '00 WR 400. I never mounted it, but I'm told that it is loud but makes good power; best used for MX, closed course or open riding areas. I believe that it will fit either a 400 or 426. It came with an extra YZ fender so it might be a YZ model. Since you are in PA I will give a refund in case you are unhappy. I live in the Monroeville area (suburb of Pittsburgh) if you are interested. The only defect that I am aware of is a SMALL dent in the outer cover. (approximate size of the tip of your pinky finger) PM or e-mail if interested. Thanks for the reply.

Is it S/A? Is it the type 2 with the replacable end cap? If it is not then I had one on my '99 yz400 and it put out 110 db. It is pretty loud but man it sounds good.
