TJ Halbleib from Snow's Polaris in Coraopolis, Pennsylvania installs a Muzzys XP 4 Dual Exhaust an a Digi-Tune Pro electronic fuel injection controller on our Polaris Ranger RZR XP-900.
The Muzzy exhaust for the Polaris Ranger RZR XP-900 features an integrated oxygen sensor bung, Full 304 stainless TIG welded head pipes, and USFS approved spark arrestors and quiet cores. The exhaust is available in three finishes; brushed aluminum, black, and stainless.
Longer dual oval aluminum muffler canisters produce that beautiful Muzzys sound without making too much noise. The trademarked Muzzler midsection cuts down on decibels without hurting horsepower. In fact, we noticed a significant improvement in the RZR's horsepower across the board and much faster throttle response after the Muzzy exhaust was installed.
In addition to the performance perks, the Muzzys exhuast weighs 6 pounds less than the Polaris stock exhaust.
Muzzys reccommends pairing their 2 into 1 into 2 performance exhaust for the Polaris Ranger RZR XP-900 with a Digi-Tune Pro electronic fuel injection controller, and we are glad we took their advice. The Digi-Tune Pro comes pre-programmed specifically for the Ranger RZR XP-900 and is one of the easiest and most effective ways to get the best air/fuel tuning. Its load-based tuning technology delivers the proper amount of fuel for every gear ratio. The Pro version of the Muzzy DigiTune is capable of removing fuel from the stock curve for optimal performance.
