I’m posting for a friend He has a Full Dual exhaust that he had on his 2011 XP 900. Only used on a handful of rides, (he needs new tires). I’m not sure which system it is. I know it has dual pipes, one on each side. He’s asking $500 before shipping. I’m sure he will move a little on price. If any questions call or text 814 330 7128. Ask for Mike.
