My stock muffler had alot of oil along the side of the end cap. Like it oozes out of the cap instead of coming out the end. I haven't put too much oil in it. Is that supposed to happen. I would think it should come out the end, not the caps side seam. Also, the expansion chamber I bought with my kit from Daemon bikes, is garbage. The welds are so crudy they are peeling, and have a ton of shavings inside the chamber. Honestly, I dont want to even connect the thing to my bike. I'm afraid it'll fall apart from the vibration and scare the crap out of me and cause me to crash. When I do purchase another expansion chamber, it will be the one from sbp.
