I currently have R-77 CF slipons and I have decided to go to the R-77 full system. Does anyone have one they want to sell? I want the Carbon Fiber but will consider the titanium also. I'm sort of pissed off at Yoshimura because the cans are the same for the slip on and the full system but they won't let you just buy the header. So I don't really want to buy a new one unless i have to.
