OK, here is some pictures of the inside of the stock muffler. Not what I thougt it would be. Any way, I cut both ends of the muffler open and on the inlet to the muffler I welded on a small shield, thinking it might dampen the sound a bit. As you can see from the pictures, there is very little packing matierial in this muffler, so I added some on the front side of the muffler, and both end caps.
To try and minimize exhaust fumes inside the RZR, I removed the exhaust tip from the back, and welded it on the bottom side.
I won't know what it truly sounds like until I get my spark arrestor installed. The bolt came loose and I lost it. Dealer ordered me a new one.
Once I get the other oem muffler that I just bought, and get the spark arrestor installed on this one, I will compare sound levels to see if it is any quieter, or if I just waisted a day of my time. I will keep everyone updated on the results.
This is the inlet side of the muffler.

This is the outlet side of the muffler.
