Product Details

This muffler is listed for 1961-1964 Ford F-100, 1966-1974 Ford Bronco, 1968-1978 Ford F-100, 1969-1974 Ford E-100 Econoline, 1973-1974 Ford F-250 with 133-inch wheelbase, 1975-1978 Ford F-150, and 1978 Ford F-250.

Common Problems It Can Address

  • Rust-through or corrosion in the original muffler body

  • Worn factory muffler on a Ford F-100, F-150, F-250, Bronco, or E-100 Econoline
  • Need for a direct-fit exhaust muffler with OE-style dimensions

Installation Notes

Verify inlet and outlet diameter, offset configuration, and overall length against the existing exhaust system before installation. This muffler uses pipe connection ends and is not reversible or tunable. Confirm vehicle-specific fitment for the exact year, model, and wheelbase listed, especially on 1973-1974 Ford F-250 applications with 133-inch wheelbase.

Quality Assurance

Walker SoundFX Direct Fit mufflers are built with aluminized steel, mechanical interior joints, and spun-locked heads to support durability and consistent fit on the specified applications. Part Number 18238 is engineered as a direct-fit replacement for the listed Ford vehicles.
