Need rv 7500 pipes. I have a 1979 blizzard 7500 plus 340 rv body style. I made a custom wiring harness to electronically accommodate a 1981 blizzard 9500 motor. Converted the sled from bosch to nippondenso cdi. Dropped the motor and carbs in. Works pretty great. Not for sale. However I need pipes. My pipes started barking and clattering like crazy, turns out the flat seam that runs the length of the pipe has begun to give way, starting with an 11 inch crack down the seam and some vertical cracks. Anyone got pipes or know where I can get either one pipe or a pair? Thanks
