I don't know if this is a repost or not but , I just got my hands on the new evoluton 80 gx and much to my surprise couldn't find a muffler for it but after much searching and a couple of phone calls found out that if you are cool and play your cards right you might just be able to get your hands on a proto type from bisson with smoke taps for $129 "inverted wrap around" pitts, but you didn't hear it from me, just figured I'd pass it on
