I’m currently running one on my 520 Foreman Rubicon, it’s definitely quieter than stock. I’m running the Silent Rider on my P7-4 now, it fits perfect and it’s also quieter than stock. No problem talking to the rear passengers. If you haven’t purchased one yet I would go with the Silent Rider, the custom fit is worth a few bucks. I paid $178 shipped off EBay BNIB.
