Walker SoundFX Direct Fit muffler Part Number 18888 is a specific-fit exhaust muffler for select Chevrolet Tracker and Suzuki Vitara/Grand Vitara applications.

Product Details

This Walker SoundFX muffler is engineered for vehicles that need a direct-fit exhaust replacement without modifying the exhaust path. The oval body measures 20 inches long, 11 inches wide, and 5.5 inches high, with an overall length of 74.375 inches. Part Number 18888 is built from aluminized steel and uses a combination muffler design to support a factory-style fit and finish on 1999-2004 Chevrolet Tracker, 1999-2003 Suzuki Vitara, and select 1999-2002 Suzuki Grand Vitara models.

This part cross-references AP Exhaust 28755 for the same application.

What It Helps Address

  • Rust-through or corrosion in the original muffler body
  • Exhaust noise that has increased due to internal muffler wear
  • Damaged or leaking flange connections at the inlet
  • Fitment issues from using a universal muffler in a specific application
  • Replacement needs on Chevrolet Tracker and Suzuki Vitara/Grand Vitara exhaust systems
