Best Polaris RZR Exhaust Systems
The internal combustion engine is really quite simple when you break it all down. It is basically just a mixture of fuel, compression, spark and air forced in one way and out the other. Getting more horsepower out of it is a matter of increasing things from one direction to the other and there are many ways to do so. One of those ways, and a popular one for the Polaris RZR at that, is by bolting on a different RZR exhaust system.
