[QUOTE="kirrbby, post: 142513, member: 3972"] I have a link and maybe some info for you. I have a cheapo Chinese pipe that I tried on my 125. It came with a removable baffle, otherwise its just a big open pipe. Nothing inside to quiet the noise etc. It's also very short. The baffle was a restriction but it would quiet the noise considerably. Without the baffle it was super loud. I drilled some holes thru the baffle for better flow but that did make it somewhat louder. It's a crappy pipe for quieting a big motor any way you shake it. I just used it for a temporary stint till I could mount my good pipe. See pics in the link for that baffle modification. You can look more into that thread for my exhaust info with that bike. Check post #86 the thread I linked in the next post. Then I mounted a Mizumoto pipe, nice pipe, that I bought from fatcaaat. It was missing the removable baffle but it has some sound damping built in. The pipe was loud but not too loud. Sounded good but I needed to quiet it at least a little for my situation. Fatcaaat found the baffle for me. He had modified the baffle similarly to what I had done with the cheapie pipes baffle. When I installed the baffle it did exactly what I needed it to. Quieted a little with little restriction. So, I'd say pick a pipe that has some sound damping and a removable baffle. Then you can still make modifications to the removable baffle, IF that's even necessary. Somewhere in the above thread there are links to a couple videos of the bike running both exhausts that I mentioned. [/QUOTE]
