MS500i Billet Exhaust / Muffler Cover
Engineered to optimize the real-world performance of the MS500i
CNC-machined from aerospace-grade 6061-T6 billet aluminum, this one-piece performance exhaust cover replaces the factory stamped steel cover with a precision-machined billet design optimized for exhaust flow and heat transfer, improving exhaust efficiency and real-world cutting performance.
By reducing restriction at the outlet and refining exhaust flow, this system helps the MS500i pull harder under load, maintain RPM through the cut, and respond more immediately during acceleration — especially when running longer bars or working in dense hardwood. This is usable performance you can feel in the cut, not just on paper.
Real-World Performance Benefits
Stronger pull under load
Improved ability to maintain chain speed through the cut
Faster RPM recovery when exiting heavy material
Sharper, more immediate throttle response
Improved heat management during sustained cutting
The optimized exhaust design also produces a deeper, more defined exhaust note that reflects the improved flow and throttle response, without sounding harsh or uncontrolled.
Premium Features
CNC-machined from aerospace-grade 6061-T6 billet aluminum
One-piece performance exhaust / muffler cover
Includes a USFS-compliant spark arrestor screen
Proudly manufactured in the USA
Compatibility
Compatible with the STIHL MS 500i.
Installation & Support
Detailed installation instructions included
Direct bolt-on installation using factory mounting points
We’re here to help — if you have questions during installation or setup, support is available to ensure a smooth, confident install.
Warranty
🛠️ Lifetime Warranty
Covers defects in materials and workmanship under normal use.
Excludes misuse, neglect, or unauthorized modifications.
