Just wondered whos gone for a slip, been thinkin long an hard about a full system or slip on and decided to go for a slip on, obviously mainly the cost difference is major but i dont think spending an extra 300 - 400 pound for lighter headers and the extra 7 or so bhp is worth it, the job of cutting the stock yamaha system is easy enuff so if you,ve gone slip on, which did you go for ? cheers guys
