HPS through extensive field and dyno testing has developed an all new exhaust silencer for the NEW POLARIS AXYS. Results: Improved performance through-out the entire power curve, increased throttle response in the mid-range, and +4 HP gain (200 RPM increase) at the top end. Compatible with the stock ECM programming. An impressive -13 lbs weigh reduction. The New Platinum Lite Ceramic is a rich metallic finish rated for 2200 degrees and twice as durable as our previous polished coating.
HPS is conscientious of maintaining respectable sound levels. This new AXYS silencer develops only 2 dbs over stock at wide open throttle while maintaining the highly desired HPS signature tone. Coupled with our Double Walled Design that greatly decreases under the hood heat and reduces harmful engine harmonics. HPS has proven their designs with supplying two decades of lightweight and durable snowmobile silencers.
