Walker 56044 Exhaust Resonator and Pipe Assembly

Walker 56044 Exhaust Resonator and Pipe Assembly

Walker 56044 is an exhaust resonator and pipe assembly built to match original-system fit, flow, and sound characteristics. It uses steel construction with an aluminized finish for a durable OE-style replacement on select Subaru applications, including Legacy, Outback, and Baja models.

Key Features

• Part number: 56044
• Exhaust resonator and pipe assembly for OE-style replacement
• Steel body and steel pipe construction
• Aluminized finish for added corrosion resistance
• 1 inlet with 2-bolt welded flange
• 1 outlet with 2-bolt welded flange
• Overall length: 63 inches
• Muffler body length: 10 inches
• Round body design with 3-inch height and 3-inch width sections

Detailed Description

Walker 56044 is engineered for Subaru exhaust repair where original fit and sound matter. The resonator is tuned to deliver OE-style exhaust tone and steady flow characteristics, making it a direct replacement choice for 2000-2004 Subaru Legacy with dual catalytic converters, 2000 and 2003 Subaru Outback with dual catalytic converters, 2001-2004 Subaru Outback with engine code EJ253 and dual catalytic converters, and 2003 Subaru Baja. This Walker 56044 assembly is built with a steel body, steel pipe, and aluminized finish to support long-term service in the exhaust system.

This part cross-references AP Exhaust 68454 and BRExhaust 280-035 for the same application.

What It Helps Address

• Exhaust resonance or unwanted tone changes after system wear
• Rust-related failure in the resonator or pipe section
• Leaks at flange-connected exhaust joints
• Fitment issues when replacing a damaged OE-style resonator assembly
• Reduced exhaust flow caused by a deteriorated pipe section

Installation Notes and Tips

Verify the vehicle’s year, model, and engine configuration before ordering, especially on Subaru Outback applications with engine code EJ253 and dual catalytic converters. Confirm flange alignment and exhaust routing before final tightening so the assembly seats correctly in the system. For best results, inspect adjoining gaskets, hangers, and mating surfaces during installation.

Quality Assurance

Walker designs this resonator to fit, perform, and sound like the original system, using tuning methods aimed at OE-style exhaust characteristics. It is a direct-fit replacement component for the listed Subaru applications.
