Application
Willys MB (1941-1945), Ford GPW (1941-1945) and Hotchkiss M201 (1955-1966) with standard passenger side exhaust system and oval silencer. Suitable for vehicles with 4-134 L-head engine.
Installation notes
Attach the flange with new gasket to the exhaust manifold. Ensure the flexible section is not under tension during installation. Verify that all mounting points can move freely to prevent breakage. Use new gaskets and check for leaks after installation.
Compatibility
Only for standard passenger side exhaust system with oval silencer. NOT compatible with deep mud exhaust or alternative exhaust configurations. Note: Hotchkiss M201 uses the same exhaust system as MB/GPW despite later production years.
Historical context
The flexible section in the front exhaust pipe was originally an essential component to absorb the significant vibrations of the L-134 engine, thereby protecting the exhaust system and manifold against fatigue fractures during military operations.
