polaris predator

[LLL]

I am going to purchase a 2005 polaris predator 500 and install an aftermarket exhaust on it. Was wondering what the horsepower/torque increases I could expect from hmf sport system. Also any advice on jetting and airbox/filter changes recommended for a stock engine. Thanks

The jetting that we used to dial our Predator in was a 155 main with the air/fuel screw set to the highest smoothest idle. More air and fuel will always equal more power but our testing was done with the intake stock.

Thanks for your timely reply. I appreciate your insight on jetting/intake. It looks like HMF has a competitive product.
