  • 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 with a nice throaty bark when fully open. Truly we believe it's one of the best sounding exhausts you'll find for the Pro-R.

  • Looking for the same note, but less sound?  You can actually adjust the sound with a manual cutout (stealth cap) that bolts into either one of the outlets.  This cap makes our exhaust quieter than other exhausts with a single outlet because the sound waves get trapped in the capped outlet.  Does the cap decrease airflow?  A little bit, but not a huge amount.  Sure open will flow a little better, but the single 2.5" outlet still flows a TON of air and is more than enough for whatever you throw at it.
  • Now available with an electronic cutout option with wire harness to adjust sound on the fly without having to install or remove a quiet cap.
  • If you'd still like less sound and/or need to be spark arrested, we have a spark arrestor for the other outlet, or both outlets if you don't run the quiet cap. 
  • Much better airflow which is needed to decrease heat (especially when tuned)
  • Level 2 ECU Tuning is required 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 side of the vehicle.  We found the side exit to sound MUCH better and make slightly more power than a center exit exhaust.
  • 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
  • The aluminum heat shield keeps the back of the muffler cool and looking badass with an AA graphics
