Whether it’s too loud, too hot, or negatively affecting engine performance, there are many things that can be done to stock Polaris Ranger Full-Size exhausts to improve the machine. Heat is an issue that many riders have come to dislike about the Polaris Ranger exhaust. Exhaust heat can make the cab of the Full-Size Ranger stifling, and it can also turn the muffler pipe a cherry hue of red. Full-Size 570 Polaris rangers have a hot exhaust, to begin with, but if you think your Full-Size exhaust is hotter than normal, you should clear / clean the spark arrestor. A cracked intake could also cause a Ranger muffler to run hot, so check the header flange where the exhaust meets the cylinder for any damage. Finally, if your Full-Size Ranger muffler is way too hot, it might be running too rich or too lean -- perhaps because of EPA regulations. You can adjust your ECU with a tune to fatten it up, and unless you run super high RPMs for extended periods of time, your muffler shouldn’t get so hot that it turns red. And if you’re feeling the heat in the cab, you can put header wrap on all the exhaust pipes up to the muffler to stop heat from rising up through the baseboards.

In addition to abnormal heat, many Full-Size Polaris Ranger owners complain about the loud noise of their machine’s exhaust. Aside from running car mufflers to lessen the exhaust noise, there are a few options one can implement that aren’t as extreme. Silent Rider, for example, makes a muffler silencer that reduces exhaust noise by around 50%. It doesn’t cause power loss or any other issue from the added back pressure, but we’ve gotten feedback from a few riders who said that they disliked them because carbon built up over time and caused their machines to lose power over time. Aside from silencers, other Full-Size Ranger owners have reduced exhaust noise with their own homemade solutions. A 2014 Ranger 800 owner that we know added about a foot onto his pipe and slightly turned it pointed to the ground using a scrap piece of stainless. Another rider we know used 3M insulation and self-adhesive pads, sticking the pads on the underside of the roof, on the panels under the seat, and on the inner fender panels to reduce in-cab noise. We all know that two cylinder engines are inherently quieter than one cylinder engines, so perhaps one day Polaris will improve the exhaust on the factory design. Until then, the aftermarket and you as a Polaris Ranger owner need to take the initiative. So feel free to contact us and we’ll do whatever we can to get your Full-Size Polaris Ranger muffler where you need it to be.
