Product Details

Walker 28013 is an aluminized steel exhaust muffler engineered for direct-fit replacement on the rear of the Ford Focus from 2000 through 2004. The oval body measures 32.5 inches overall, with a 9.75-inch body width, 4.25-inch body height, and 9-inch body length. Its pipe connection inlet and tip-style outlet are arranged in an offset configuration to match the listed application.

The SoundFX Direct Fit product line is aimed at replacement buyers who want a muffler that installs to the vehicle-specific layout while supporting a controlled exhaust note. This part cross-references AP Exhaust 7453 for the same application. Walker 28013 is a practical choice when replacing a worn or noisy rear muffler on a Ford Focus.

Common Problems This Muffler Can Address

• Exhaust noise from a rusted or damaged rear muffler
• Loss of factory-style exhaust tone after muffler failure
• Corrosion-related deterioration of the original steel muffler
• Fitment issues caused by using a universal replacement instead of a specific-fit part
• Visible exhaust system wear at the rear of the vehicle

Installation Notes and Tips

Verify the rear muffler layout, inlet offset, and 2-inch pipe connection before installation. This muffler is not reversible and is not tunable, so orientation should match the vehicle’s exhaust routing. Confirm clearance around the oval body and outlet tip location during test fitment on the Ford Focus.

Quality Assurance

Walker uses 100% aluminized steel in this SoundFX Direct Fit muffler to support longer service life than low-carbon steel construction. Mechanical interior joints and spun-locked heads add structural durability for everyday exhaust service.
