Description
Overview:
This is a genuine Stihl exhaust pipe designed for selected Stihl petrol hedgecutters, including HS 81 R and HS 81 RC. Made from durable metal (formed steel), it routes exhaust gases safely away from the engine while helping maintain the correct backpressure for smooth running. The pipe replaces worn, cracked, or damaged originals and restores proper exhaust flow, which supports reliable starting, steady idle, and consistent cutting performance. As an original Stihl component with MPN 4237 140 3400, it is engineered for a precise fit on the specified models and integrates with the existing muffler assembly. Suitable for professional and domestic use, it keeps the machine operating efficiently and helps protect nearby components from heat.

- Genuine Stihl OEM part (MPN 4237 140 3400) for assured compatibility and quality
- Direct-fit replacement for the listed hedgecutters; no modification required
- Robust formed steel construction resists heat, vibration, and impact during regular use
- Maintains correct exhaust flow and engine backpressure for reliable performance
- Helps protect bodywork and nearby parts from hot exhaust gases
