The Polaris Sportsman 850 XP is available as a Slip-On system in the Titan and Swamp (with snorkel) exhaust. The Slip-On System picks up 3-4 more horse power throughout the power curve, and adds an incredible sound to the machine. The Titan/Swamp-Quiet exhausts are roughly 1-2dB louder than stock, while the Titan/Swamp-XL are 4-6dB.
Fuel Tuning is absolutely required when installing an HMF Exhaust on this machine. Failure to tune the engine can cause excessive damage to the exhaust system and engine, while voiding the warranty on your exhaust and possibly on your machine. (check with local dealer). See the tuning settings below for the proper fuel tuning solution on your machine.
