On my last high speed get off of my 07 WR 450, one of the damaged items was my silencer. The tubing is kinked enough that it is beyond saving.:thumbsup: Being broke, and needing to get back on my bike, I found a 06 YZ 450 silencer for pretty cheap. I know it won't have a spark arrestor (dont worry, I'll fix it), but will it bolt up to my bike? I didn't know if the aluminum frames were a copy from the YZ's or not. It obviously doesn't have the same part number, but anyone know if it will work, or do I keep shopping?

i do not know if it is a copy of the 450's or not but i can tell you to widen your search. 06 to 09 will fit your bike

That's good news. If a 06 YZ will bolt up, I might be riding soon.:thumbsup: I wish I could buy a brand new trick $500 piece, but my pockets just aren't deep enough lately.:confused:

I'm running a YZ450 06 muffler on my WR450 07. Bolts up fine. The only thing is that the WR header is a smaller diameter. I had to use some exhaust tape to seal it properly.

I have since put a YZ450 08 titanium header on. It is even bigger diameter than the 06 YZ header. I had an exhaust shop expand the clamp section of the tube and i installed a new YZ450 08 gasket. Its all good now!!!
