Product Details

Walker SoundFX Direct Fit is a product line focused on replacement mufflers that match vehicle-specific exhaust layouts while maintaining a clean appearance and controlled exhaust tone. This Walker muffler uses 100% aluminized steel for improved service life versus low-carbon steel, along with a combination muffler design suited to factory-style exhaust service on Camaro and Firebird platforms. The oval body measures 24 inches overall, with a 19-inch body length, 9.75-inch body width, and 4.25-inch body height. It features a 2.25-inch inlet and dual 2-inch outlets, making it a practical replacement for select dual-outlet exhaust configurations. This part cross-references AP Exhaust 700276 for the same application.

  • Rust or corrosion in the original muffler housing
  • Exhaust noise from a worn or damaged muffler core
  • Fitment issues when replacing a factory-style direct-fit muffler
