Hello to all you WR owners. I posted this message in the YZ forum but figured you might be able to help also. The problem is this:... I own a Yz426 and like to ride at the Silver Lake sand dunes in Michigan. Well they just passed a new requirement of 94dB max noise. And im thinkin the stock Yz426 exhaust wouldnt pass. It was brought up to me that i should put a WR silencer on my bike. This raises a few questions. First off, will it fit? Second, would it meet the dB requirement (2500 RPM, 20 inches away from rear of pipe)? And does it have a spark arrestor? Any info is greatly appreciated. And if anyone has a silencer for sale, i may want to take it off your hands. Thanks in advance! :)

I have a 01 wr426f muffler for sale. Practically brand new, there is only soot on the top of the inside. Has a baffle and should fit. Don't know the decibals though. I will get rid of it for $40 +S&H.

Dan Lawrence, any way i could see a picture of it? And what is the inside diameter of the pipe where it would slip on to the headpipe. If you can get a pic, please send it to quadridermx@juno.com . I am very interested in purchasing it, but just want to make sure it will for sure fit before i fork out the moola. Thanks

Here's a post I did a few weeks ago with sound level measurements for various mufflers:

Useless muffler statistics

And a WR muffler should fit your bike just fine.

It is in great near new hardly ever used condition. The inside is barely sooted. I don't have access to a digital camara. I am still in the dark ages using 35mm. I will measure the inside diameter when I get home. I am on 24hour duty tonight. (They need a sleepy icon) :)
