I have an 2004 500cc cat. It pretty much stock the previous owner told me he put a little richer jet in because he'd take it into the mountains in Colorado. I'm trying to do the muffler mod and I cut the very back part of the muffler off and it exposed a baffle plate with 3 tubes welded in it. After I saw that I checked the pictures people have posted on here of gutting their muffler and it looked nothing like what I've seen. So I cut just a hair more off the muffler just to get past that baffle plate and now I've exposed another baffle with 1 tube that comes out of the center of it, stopped just before the baffle I cut out and then it would vent into the 3 little tubes. Do I need to take this baffle out as well? I've tried grabbing the tubes with pliers and working it and the next baffle out but it would only wiggle up about 1" and stop. I just want to make sure I don't drill a bunch of holes in this baffle and find out there is still another behind me and have accomplished nothing. I hope this makes sense to everyone. I see where several people have posted 4 evenly spaced tubes in the center of their muffler but I haven't found that yet. Do i need to go further?
