I use my RZR for hunting and never ride in dunes. So power is not a concern to me. Anybody know of a company that makes a REPLACEMENT muffler that mounts in the same location as the stock muffler? I know all about the ones that you can buy to slip on the stock tailpipe but they hang off the back of the machines. Like the Benz or the SLP. I would prefer it to be mounted underneath and looking for something ALOT quieter than stock! Anyone?
