I have not posted a message before, but since I have spent over an hour looking for my answer and can't find it I need help. I bought a new 08 WR450 (last year's model, new) and I am in the process of doing all the modifications the factory should have done in the first place. It's pretty bad when my 99 WR400 woops its ass all over the place. I bought the TT kit, jets, needle, and promoto billet for the exhaust. I am starting with the exhaust. I pulled the end cap off the exhaust along with the stock insert. I also removed the two rivets holding the end piece on. Here is my question. How do I get the end piece off? I have tugged on it, even put the insert back in for more leverage as I pull. I don't want to mark up my pipe. How in the hell do I get it out so I can gut out the plugged up pipe? Any help is appreciated!

I seem to remember having troubles with my 07 as well. I think I removed the exhaust and may have had to pound the pea-shooter in a bit to break any residual rivet metal. Then I think I could pull it out.

Thanks for the reply! I tried using a scew driver and a hammer to punch it into the pipe last night. I managed to move it anbout 1/16 of an inch. How far can I push it inward before I start doing any damage? The thing is still way tight. I can not get it to budge outward. Any ideas? Anyone else have any insight?

I did go through all of those before I posted this originally. I learned a lot, and I know exactly what to do onces I can get the end piece off and get to all of it. I just don't want to bend my end piece and mark up my exhaust. I will work on it again tonight, hopefully this time with no swearing.

You might have to try a slide hammer to get it out of there. If you can get one with a fairly large "L" shaped fixture you might be able to get it moving through the exhaust port. :p WR Dave

I got it! I ended up going to the hardware store and picking up four bolts that were two inches long and fit the four holes (bolts) in the end piece. I drilled four holes in a piece of wood, used four washers, put extended bolts through washers-wood-end piece. I turned them one turn each at a time until the end piece moved to the end of the exhaust. Once I removed the bolts and wood it only took a little tug with my fingers and it popped right out. Hope this helps someone in the same situation as myself. Thanks Bradsind and WR Dave for the suggestions.
