Aftermarket Assassins ’22-’25 Polaris RZR Pro-R 4 Cylinder Full Exhaust

• Gain 14-15rwhp peak/10-12rwhp max (roughly 15-20 crank hp) and the motor revs much faster
• Looking for a full stainless steel exhaust that looks great, sounds great and has adjustable sound levels while producing the most power possible? Look no further!
• The OEM header is an odd 2 into 2 into 1 design and has many areas to improve upon. We set out to make a functional header that looks great.
• Our header is engineered to have equal length runners into the collector
• Stainless steel stepped header design for improved flow and longevity
• Header does not use factory heat shielding
• Header includes a new gasket where it meets the cylinder head
• We design, build, and ship everything in house. Our header design has straight runners and goes around the frame rail like OEM which simply makes power. Other headers may look great and run inside the rail, but they will not perform well because of the sharp bends off the head.
• This exhaust sounds amazing and is one of the quietest exhausts with the cutout closed. It has an absolute wicked formula car sound when fully open. This is one of the best sounding exhausts you’ll find for the Pro-R.
• Center exit exhaust with a chambered muffler. This design uses your OEM tip/spark arrestor making it a very quiet exhaust with the 3″ side dump closed with optional 3″ Stealth Quiet Cap. Open up that 3″ side dump and let it scream when you want to!
• This center exit design with 3″ cutout allows for wild and mild sounds in seconds by bolting/unbolting the 3″ Stealth Quiet Cap, or the flip of a switch if you choose to upgrade to the electronic cutout.
• Electronic cutout comes complete with the wire harness
• Much better airflow which is needed to decrease heat (especially when tuned)
• Level 2 ECU Tuning is HIGHLY suggested with the full exhaust – see our ECU Flash for more details
• Eliminates the stock catalytic converter providing much less engine/exhaust heat (header glow is MUCH less)
• Sheds a huge 14lbs off your machine!
• Fits nicely into the factory mounting location
• Uses top and bottom OEM rubber mounts. Beware of exhausts that have any solid frame mounts as they will crack the head pipe!
• Exhaust exits out the center and the side of the vehicle. The side exit dump works well for max horsepower gains as it bypasses several exhaust chambers, and we found the side dump to disrupt flow the least as the exhaust does not have to turn to exit. Made at the AA Facility in the USA
• Sharp corners and outlets designed to match the RZR styling
• Hydro blasted finish with rust inhibitor compound (yes even 304 stainless will rust in the right conditions)
• The stainless will bronze and matches the stock header very well
• Fits all 2022-25 RZR Pro-R 4 Cylinder models
• Made at the AA fabrication facility in the USA (Wisconsin)Sound Clip: /shorts/R-2MlMUBAKI
