Power increased by 10hp & 15ft/lbs of torque providing Rapid Torque & Horsepower gains!

What can a 4 Predator Performance Exhaust System do for your H1? Dramatically improve your H1s tone, increase in horsepower, and Fuel Economy.

Having that extra boost in power can also make your life a lot more fun in off-road terrain. Giving you that extra push you need to keep from getting stuck. If you live at a high elevation and often find your H1 struggling a little to climb steep roads, the extra power added by our 4 Performance Exhaust System can help you out there too.

The Off-Road Pipe removes your catalytic converter for off-road performance gains and constructed of high quality stainless steel.
