Installed the Stealth Quad pumper system (item #2140) on my CanAm X3 Max. Pump was easy to install, I recommend the billet mount for the X3 (item #2871).
Works great so far for all 4 helmets. Weather is colder outside right now, so we will have to wait for a summer time review.
Installed this in my RZR XP4, install was fairly straight forward. Only thing I wish I would have know was the power draw off this unit. If I leave the unit on for more then a few minutes with the engine off it will kill the battery. Also without upgrading the stator running multiple systems, pump, fans, lights, radios. The voltage drop even running is significant.
Used three outlets plugged the fourth. The air was great, kept the dust down and kept us comfortable.
Purchased the stealth quad air for XP4. Used it in Glamis for the first run and worked perfect. Had a single pump before and no match in air compared to the PCI RaceAir system.
