Yes, I forgot there is also the DG pipe on Ebay, but the header pipe that comes with it won't work, because it is bent like the stock Trizinger header pipe. It will Interfere with your kick stand as is. I've never heard of dynoport pipe. It looks pretty sweet, but I imagine it's a pipe that's no longer produced since you said it's rare and I imagine that it would be pretty tough to find one. If you know of a source, Let me know because I'd like one for myself!
