I have a NOS can around my shock resevoir. I think it's funnier than hell that I can actually convince some people it's NOS. "No I swear, it's a Real NOS can!" <technically true, lol>. It's a pretty common mod and a simple one. Some people hate it, personally I think that the cylinders are way too plain and don't mind seeing them covered up with something with a lil humor and/or style to it, seen one that was wrapped in that fake stickon carbon fiber, looked pretty nice and I'll prolly do that after I get tired of the NOS can.
