A beautiful CNC machined billet end cap is attached to the end of the system for good looks. We also noticed all connections have been joined by very nice TIG welds.
Our '09 Polaris RZR-S has been so much fun we almost don't even want to modify it ... almost. Who can't use a few extra ponies and sleek stainless steel bling? The stock exhaust on the RZR-S is pretty quiet, which we enjoy, so when we decided to upgrade the exhaust we searched for something that also wouldn't shatter ear drums. Meeting all of our requirements was the new HMF Swamp XL Series exhaust system.
What Did We Think?The new setup looks amazing, has almost a stock-like sound that is deeper (not louder), and was super easy to install. According to HMF, the dyno numbers report a gain of 3 to 5 hp from low- to high-range with no EFI calibration needed. Pretty good for a quick and easy upgrade!

All new hardware is included and no cutting or welding is required. We do recommend removing the factory bed from the rear of the vehicle to make the installation much easier. |
