I'd go the slip on route before putting ANY money into a ten year old muffler especially when after the new end cap and packing you would be two thirds of the way to the cost of a slip on.

'06 WR silencer is made out of Aluminum. Would this retro-fit back to the 426's? Maniac

If you need a spark arrested silencer I do not believe a YZ pipe will work.

sound doesnt bother me as long as its legal for the parks around me which is i believe 96db. if i get the yz pipe do they have the sparkarrestors in them already and could i get in trouble for havin that on a green sticker but the rangers thinkin its a red sticker?
The stock YZ pipe does NOT have a S/A. This is why many have recommended it in addition to the pipe. I would also suggest the quiet insert because without it you won't be anywhere near 96db. My bike actually failed the test at Hollister with the quiet insert although it wasn't over by too much.
As for the Green/Red sticker issue it doesn't really matter. Even a Red sticker bike is required to have a S/A if opperating on public land.
My advice is that if you want to switch pipes - find a nice stock YZ pipe and install the S/A endcap and quiet insert or buy an aftermarket slip on such as the FMF Q or similar pipe made for offroad use. Stay legal and you will never have to worry about it.

...this bike is a blast!
Amen to that!! Make sure you do the free mods if you have not done them already to really wake up the beast. The O-ring mod is the single best mod you can do (besides the throttle stop) IMO.
Also, make sure you put something under the chain slider. It does not fit snugly and can wear the top of the swingarm, and I think has even caused failures in extreme cases. I siliconed on a piece of old innertube I cut to shape to protect the swingarm. It protects as well as raises up the slider, allowing the screws to hold it down much better and reducing chain slap noise.
