Detailed Description

Walker Part Number 18830 is a direct-fit exhaust muffler engineered around the original exhaust layout for 1998 Chevrolet Tracker, 1994-1997 Geo Tracker, and 1996-1998 Suzuki Sidekick models.

Common Problems This Part Can Address

• Rust-through or corrosion in the original muffler body

Installation Notes and Tips

Confirm the inlet and outlet configuration against the existing exhaust before installation. This muffler uses a center 2-bolt welded flange inlet and an offset 1.75-inch tip outlet, so matching the vehicle’s original routing is important for proper alignment. Verify clearance around the oval body and overall length during mock-up, especially on 1994-1997 Geo Tracker, 1996-1998 Suzuki Sidekick, and 1998 Chevrolet Tracker applications.

Professional exhaust installation is recommended to ensure correct sealing, hanger alignment, and final positioning. Part Number 18830 is a direct-fit replacement, so the best results come from matching the vehicle’s original exhaust configuration.
