Stihl Exhaust Pipe - OEM Number: 4237-140-3402

The Stihl Exhaust Pipe (OEM 4237-140-3402) is a replacement exhaust component designed for compatible Stihl HS-series petrol hedge trimmers. It forms part of the engine exhaust assembly, directing hot combustion gases away from the engine and through the appropriate exhaust outlet while helping maintain the correct exhaust flow. Stihl parts information lists the component as an exhaust gas tube and shows it within the exhaust assembly of compatible machines.

Manufactured for the high-temperature environment of a two-stroke engine, the exhaust pipe provides a secure connection between the engine's exhaust components and outlet arrangement. Replacing a cracked, distorted, corroded or damaged pipe helps restore proper exhaust routing and protects surrounding components from excessive heat and exhaust gases. The part is listed for HS 82 and HS 87 hedge trimmers, including R, T and RC-E variants.

IMPORTANT INFORMATION

The exhaust pipe should be inspected whenever the muffler or related exhaust components are removed, particularly for cracking, distortion or corrosion. The associated exhaust gasket and fixing hardware should also be checked to ensure the assembly is correctly sealed and securely mounted.

Always check the exact machine model and serial number before ordering, as Stihl exhaust assemblies can vary between machine versions. The OEM number should be matched against the existing component or the machine's parts information to confirm compatibility.
