Any time your side by side is running, it is producing waste products. These waste products include hot, toxic gasses that must be expelled from the engine at once. A good exhaust system will always expel these waste products in a timely fashion. However, the opposite could result in serious damage and frustration. For one, your side by side may become obnoxiously loud like your crazy ex. Your side by side could also overheat, resulting in damage to your engine’s parts. Additionally, your side by side’s performance will begin to drop as a result of engine damage and poor fuel economy. Need a great exhaust system? Want to upgrade your stock exhaust system? Your best option is the Polaris RZR Performance Series Dual Full Exhaust System. This dual full exhaust system by HMF Engineering gives your ride up to 4 horsepower at high RPM and adds as much as 2lbs of torque. Give your ride an edgy look with mounting locations on either side of your side by side.
