Description
Overview:
The Exhaust Casing 1128 145 0803 is a genuine Stihl replacement part for professional and domestic chainsaws. It is a heat‐resistant metal housing that covers and protects the exhaust outlet, helping to manage hot gases, maintain correct back pressure, and shield nearby components. Designed for selected Stihl machines such as the 044 and MS 440, it restores proper exhaust flow when the original cover is damaged, corroded, or missing. A correct casing helps reduce leaks, supports consistent engine performance, and contributes to emissions control and user safety. Built to Stihl's fit and finish, it installs in place of the original unit using the existing fixings on the saw, making it a straightforward maintenance item for routine servicing or repairs.
Key Features:
- Genuine Stihl part for assured compatibility and fit

Typical Applications:
Used when the original exhaust cover is dented, cracked, corroded, or missing. Suitable during routine overhauls, after impact damage, or whenever exhaust leaks, excess noise, or heat exposure are noticed.
