Transform your Can-Am Defender HD11 with the RPM 2/3 Exhaust System, a complete bolt-on upgrade that replaces the restrictive factory muffler and mid-pipe for improved exhaust flow and performance.
The larger exhaust diameter delivers noticeable power gains on stock machines and even greater improvements on tuned setups, all while maintaining near-stock sound levels and excellent drivability.
Built from durable 304 stainless steel with precision TIG welding, the system reuses the factory mounting points and includes donut gaskets and new rivets for reinstalling the mid-pipe heat shields. Factory heat panels can also be reused if desired.
The result is better airflow, lower operating temperatures, significant weight savings, and improved performance without sacrificing everyday usability.
Key Benefits:
- Power Gains: 3-5 HP on a stock HD11. Tuned machines see substantially higher gains thanks to the less-restrictive 2/3 design.
- Refined Sound: Slightly louder than stock at idle for that satisfying head turning startup, but remains very close to stock dB levels in the mid to upper RPM range. No excessive drone.
- Cooler Operation: Lowers EGTs & less bed heat
- Easy Installation: Direct bolt on using all factory mounts and hardware. No cutting or modifications needed.
- Lightweight & Premium Build: TIG welded 304 stainless steel construction for lasting quality and finish.

- 1 dB louder than stock at idle
