Rzr 570 quiet exhaust

Recently purchased a 2013 570le to take to Colorado this fall. I’m getting geared up for the trip and for now I have a dalton clutch kit for altitude but wanting to not be a nuance when letting in warm up and up the trails. I have not found anything to buy and wondering if I can rig something up to make less noisy, old car muffler or modify a kolpin. Any advise is appreciated!
