Polaris RZR 1000 Stainless Steel AK-47 Exhaust System. Manufactured exclusively in the USA by Bills Pipe for Adventure Kings. Our exhaust provides a sporty look, satisfying tones and provides increased performance all while maintaining safe AFR’s and EGT’s. With simple bolt-on installation and no need for a computer reflash this is a no brainer. As an added bonus, the AK47 is half the weight of the OEM system and the passenger side exit allows for the use of our optional OutbAK storage box.
