I have for sale a Big Guns Exhaust that was just repacked at Big Guns and a Power Box fuel injection performance box with instructions for sale. I just purchased a 700xx that had these performance Mods on it, and the power is just to much for me, so its for sale. The exhaust is very loud. All parts are in great condition. $300 + shipping and its yours. Parts are in Arizona 85254. Please call with questions 480-466-9696 Christopher
