Purchased this as a replacement for my stock '98 polaris 500 muffler. It was over $100 cheaper than OEM replacement from the dealer. It was a perfect fit and attached easily to existing mounts. It's looks great. However it is LOUD! Much louder than my original stock muffler. I wasn't expecting to sound like a race machine. Price is right but I wouldn't purchase again only because of the decibel issue.
