Some Polaris Ranger owners use their rigs for hunting and need ways of silencing the exhaust as the standard Mid-Size exhausts are quite noisy. Aside from trading in your Mid-Size for an electric Ranger, there are ways to keep the noise emissions from the exhaust to a minimum. Auxiliary hunting mufflers -- like the Silent Rider brand for instance -- do help, however, the issue then becomes engine and clutch noise. You could also try the Sportsman 570 exhaust -- they whisper quiet. Additionally, running insulation under your seat and on all of the plastic underneath can help dampen noise as well -- the heat deflection stuff works particularly well. At the end of the day, however, the best way to sneak up on an animal is to walk.
If it is not noise, but rather heat that you’re worried about, altering or replacing the muffler and other Mid-Size exhaust components can help. Exhausts can glow red and the overflow tube can burp, in which case it is likely that your Ranger is running way lean and overheating. If you continue to ride it you run the risk of popping a head gasket. this is an issue we’ve seen on quite a few Polaris Ranger Mid-Size 570s. Slip-on exhausts and exhaust tips can also help keep the heat at reasonable levels, and some redneck Ranger owners have even resorted to drilling ½-inch holes in the bottom of their muffler, claiming that it makes it run better with less heat and less mud and water blockage. Similarly, many Mid-Size Polaris Ranger owners have asked us what would happen if they just left the spark arrestor out of their exhaust? Contrary to popular belief, it does not create or reduce any back pressure that the engine needs. In fact, if you leave it in it will burn out eventually. But watch out if you ride National Forests without a spark arrestor, as most nationalized land in the US and other developed countries have a burn ban, and you can get stopped, checked, and fined if you don’t have a spark arrestor.
