My '92 XCR 440 came with DG pipes, but i dont believe that they are available anymore. I coated them with Swain Tech coating, but there seemed to be noticable change. As far as intake i gutted out my air box. My clutch kit affect my exceleration drastically, it was an erlandson performance kit. I did 92mph on radar one day and the sled didn't go much faster than that. I wish i hadn't done all this though, because unfortunately i lost my crankshaft later last season and was forced to sell my sled later in the season.
