Exhaust System & Spare Parts for Willys Jeep CJ3B
Manifold Gasket, Head Pipe & Tailpipe for Reliable, Leak-Free Exhaust Flow (1953–1964).
Why the Exhaust System on the Jeep CJ3B Wears Out Over the Years.
The exhaust system on the Jeep CJ3B's historic 4-134cui engine (L- and F-head) faces decades of heat, vibration, and moisture – wear here is a normal part of aging for a classic vehicle. Manifold gaskets harden and lose their seal, letting exhaust gases escape and reducing engine performance. Head pipes, center pipes, and tailpipes rust from the inside out, accelerated by condensation on short trips and constant temperature swings between cold and heat. The gasket between manifold and head pipe also settles over time and starts leaking. Anyone restoring their CJ3B or getting it ready for regular driving should inspect the full exhaust system for rust, loose connections, and worn mounts – not just for noise, but for safety, since leaks can let exhaust fumes into the cabin.
- Gaskets: The manifold gasket set seals the transition to the exhaust manifold, and the exhaust gasket sits between manifold and head pipe.
- Head Pipe: The head pipe for L- and F-head engines.
- Tailpipe: The tailpipe safely routes exhaust gases to the rear.
- Center Pipe: The center pipe connects the front pipe and the muffler.
