I dropped my bike in a rock pile denting the fmf pipe right on the sticker making it fall off shortly after installing the pipe, it didn't hurt anything else tho so I don't care lol.
I've seen the stock pipe guard installed on a fmf pipe some where on this site, if you do a search it should come up.
They had to make a mount that wraps around the pipe to mount it. This was done to keep the pipe from melting a saddle bag tho not for tip over protection.
