Aftermarket Assassins Polaris RZR XP 1000 & RS1 Stainless Slip-On Exhaust
Aftermarket Assassins Polaris RZR XP 1000 & RS1 Stainless Slip-...
1 / 8
AFTERMARKET ASSASSINS
A stronger exhaust note. Six pounds less than stock.
This USA-made stainless slip-on replaces the factory muffler on the 2015–2023 RZR XP 1000 and 2018–2022 RS1. It mounts in the factory location, retains the factory O2 sensor and includes an aluminum heat shield. Choose the open dual-outlet setup or add the Stealth Quiet Cap to reduce sound.
Built for these machines
XP 1000: 2015–2023
RS1: 2018–2022
Not the exhaust for a 2024+ XP 1000 or a turbo model.
Choose your sound
No Quiet Cap: both outlets open.
Add Quiet Cap: a removable cap closes one outlet for less sound. It remains louder than stock.
Pick the correct year option
2015–2017 XP 1000
Select 2015–2017 (Smaller O2 Bung).
Exhaust part number: 110-1002.
2018–2023 XP 1000 / 2018–2022 RS1
Select 2018+ (Larger O2 Bung).
Exhaust part number: 110-1005.
The selector's “2018+” label applies only to the model years listed above. It does not extend fitment to the redesigned 2024+ XP 1000.
How loud is it?
AA reports approximately 88 dB for stock, 92 dB with the Quiet Cap and 96–98 dB with both outlets open. These are the manufacturer's comparison figures; actual readings depend on the machine and test conditions.
No Quiet Cap
The more pronounced, open exhaust note. The optional cap is not included with this selection.
Add Quiet Cap
Includes the Stealth Quiet Cap, which bolts into either outlet. AA reports no horsepower loss from capping one outlet on the naturally aspirated 1000 engine.
Spark arrestors: AA states the factory spark arrestor fits without modification. Use one with the Quiet Cap, or two when both outlets are open. A quiet cap is not a spark arrestor; spark arrestors are not an option included in this listing.
Plan for tuning before you order
AA recommends its Level 2 tune. The manufacturer says this exhaust can run on the factory tune, but the engine will run lean in the low-to-mid range. A tune or tuner is not included with this exhaust.
The six-pound weight saving is AA's comparison with the stock muffler. No standalone horsepower gain is promised here: results from an exhaust, tune and clutch package should not be treated as an exhaust-only result.
Construction, mounting and finish
- Stainless steel construction made at AA's USA manufacturing facility.
- Factory-location mounting with laser-cut brackets and hairpin clips securing the upper muffler mounts.
- O2 bung sized for the factory sensor of the selected model years.
- Aluminum heat shield with AA's graphics.
- Current production has a lightly polished, tumbled finish that develops a bronze tone after running.
Photo note: the manufacturer photos show the earlier hydroblasted finish. The supplied finish may look brighter before use.
What your selection includes
One AA stainless slip-on exhaust assembly with its aluminum heat shield and the O2 bung for your selected fitment. The Stealth Quiet Cap is included only when you select “Add Quiet Cap.” This is a slip-on muffler, not a full header system.
Match your model, year, O2-bung selection and cap choice before adding to cart. Check the selected option's availability shown above for current ordering status.
