Performance-  15-20% power increase with open airbox & performance air filter, 20%+ with Velocity Intake

Excellent throttle response, unbeatable mid-range and over-rev power

Spiral Core design-  More Power / Less Noise

1.875 inch spiral perforated core for better sound dissipation with a wide open design. 

That equals maximum power gains with less noise than other open pipe designs! 

92-95db idle with spark arrestor installed, not a 'quiet' design

Short and Fat-  11 inches long 4.5 diameter  

At 11 inches long it’s keeping the weight down, over 1 inch of sound absorbing packing depth throughout. 

Tough .120 wall thickness aluminum muffler is designed for "collision resistance" to last the life of your quad

Lifetime Warranty- protects against defect in materials and craftsmanship

Can be later upgraded to a true Competition Full System- 

Competition-Stepped Headpipe and replacement 2-inch diameter mid-pipe will turn your slip-on into one of the best performing full systems on the market for under $200
