Fat Boy 4 Exhaust System Boosts Power

Duncan Racing International has come out with a Fat Boy 4 four-stroke power exhaust for the Polaris Predator 500.

Duncan Racing says the Fat Boy 4 pipe provides outstanding throttle response and excellent midrange pull. The company also says that your machine will gain about 7 horsepower when this exhaust system is used in conjunction with a Pro Flow Kit and Vortex X10 CDI.

The pipe features stainless steel headers, mid-pipes and tail sections, with an aluminum muffler body. The exhaust system costs $649.

But an H-Q version, which reduces sound output by three or four decibels, costs $699. This system includes a bolt-on turndown and a spark arrestor screen, which are options for the regular system.
