I just bought a 12′ 570 off a buddy. he has done all the normal mods ,doors,windshield, all that I put 4 point harnesses in it and a radio. Other than a k&n filter engine is stock. curious about exhaust? considering making a change but don’t want anything load. I’ve also heard some things about getting ecu reprogrammed which will get it back to the original polaris spec before it was detuned before release. ( I’ve read the 570 would out running the 800 top end before that so the detuned them ) has anyone done this and how is your experience with it if so? I don’t want to do any mods that might hurt reliability
