Pro-Series Exhaust for Polaris Pro-R

Our complete exhaust system is designed as a package, not just a header with a separate muffler.  The primary and collector lengths have been tested in dozens of combinations until we found this combination.  This combination of 1-3/4" primary tubes that step up to 1-7/8" before sliding into a true merged collector with precisely sized venturi.  From the venturi the exhaust opens up into a 3" collector that turns inside the chassis tubes and bends right into the muffler to maintain the correct overall system length.

Liteweight including the lightened CNC machined 304 flange

Optimal stepped primary tube diameters

Shorter length primary tube length to accentuate the 8,000-9,000rpm range where race clutches are set to run at

True 4 into 1 merged collector with venturi 

Optimal collector length for maximizing power in the 8,000-9,000rpm range

100% 304 stainless construction including the complete muffler

Muffler baffling and packing that won't blow out prematurely like so many of our competitors
