So an update -- last night I attacked my stock YZ426 exhaust with a drill and took out what was left of the packing. Now my questions --

There does not appear to be a spark arrester. I assume that's needed for any sort of park riding. So, how do I go about getting a spark arrester for it?

Is there a way to mount an aftermarket silencer tip to the stock YZ426 exhaust?

Anyone have any experience with the dBDawg insert?

I've used the db dawg, noticeable decrease in sound, and not really any power loss(maybe slightly but hardly noticeable)
