Used SLP 09-122 muffler for RZR Pro XP & Turbo R. Does not come with spark arrestors but holes are drilled. Only used it for 472 miles. Had thermal ceramic coating put on by Knott Hott in Emmett. Some of the coating came off from sand coming off tires. The rest is mud staining but the coating is still intact. Paid $720 for it last year. Will take $400 BUT NOTHING LOWER, cash only.
