AA Stainless Slip-On Exhaust for 2015-Up RZR 900 S, Trail, XC

The Aftermarket Assassins Stainless Slip-On Exhaust replaces the small factory muffler on the Polaris RZR 900 S, Trail and XC with a dual outlet design that flows more air, runs cooler and lets you set the sound level.

Why it holds up

• Made from stainless steel at the AA manufacturing facility in the USA
• Dual outlets flow much better than the small OEM outlet, which helps cut heat
• Sheds 6 lbs off the machine
• Laser cut brackets for durability
• Adds 5 to 7 RWHP when used with AA tuning

Fits

• 2015 and newer Polaris RZR 900 S
• 2015 and newer Polaris RZR 900 Trail
• 2015 and newer Polaris RZR 900 XC

In the box

• Stainless slip-on exhaust with brackets

Good to know

• Sound levels: stock exhaust 86 dB, AA with quiet core 92 dB, AA wide open 96 to 98 dB.
• The optional Stealth Cap bolts into either outlet to cut sound. On the naturally aspirated 900 it costs no horsepower.
• The factory spark arrestor fits right in with no modification, in one outlet or both if you skip the Stealth Cap.
• Fits the factory location. The exhaust mounts slightly crooked but looks straight once the plastic rear shield is on.
• No heat shield on this model since the OEM plastic covers everything but the outlet.
• Tumbled to a lightly polished finish that turns bronze after running. Some photos show the earlier hydro blasted finish.
• Works with the factory tune but runs lean in the low to mid range. AA recommends its Level 2 tune with this exhaust.
• Average lead time of 1 to 3 business days before shipping.
• The sound clip below is the same style exhaust on a Polaris General, which sounds the same.
