Walker SoundFX Direct Fit Muffler

Walker SoundFX Direct Fit muffler Part Number 18895 is a specific-fit exhaust muffler for select Buick Century and Pontiac Grand Prix applications. It uses 100% aluminized steel for improved service life versus low-carbon steel and is built for a clean OE-style appearance with controlled exhaust sound.

Key Features

  • Specific-fit exhaust muffler for direct replacement applications
  • Oval muffler body with a 2-inch inlet and 2.25-inch outlet tip
  • Offset inlet and offset outlet configuration
  • Aluminized steel body and finish for corrosion resistance
  • Mechanical interior joints and spun-locked heads for added durability
  • Combination muffler design for balanced exhaust tone

Product Details

The Walker SoundFX Direct Fit line focuses on replacement mufflers that match the vehicle’s original exhaust layout while maintaining a quality appearance and predictable acoustics. Part Number 18895 measures 27.75 inches overall, with an 11-inch body width, 5.5-inch body height, and 15-inch body length. The 2-inch inlet uses a pipe connection with a 3.75-inch offset, and the 2.25-inch outlet uses a tip-style connection. This makes it a practical choice for drivers looking to restore exhaust function on a 1997-2005 Buick Century or a 1997-2003 Pontiac Grand Prix, including 1997-2000 Pontiac Grand Prix models with single exhaust.

This part cross-references AP Exhaust 700333 for the same application.

  • Rust-through or corrosion on the original muffler body
