The kids at Speedwerx just dropped off their latest exhaust product at our ATV World doorstep this past week. The new slip-on exhaust system for the 2008-2013 Polaris RZR 800 line of buggies is said to produce a nice 10% boost of ponies. We like those numbers, plus the system has a built in internal spark arrestor and decibel rating of 96 db, which means the rumble is cool but not obnoxious. No chassis mods are required and the slip-on comes with complete installation instructions. No EFI controller is necessary for the boost in ponies, but you can inquire about one and experience even more goodness. Learn More Here
