Walker 55489 Exhaust Resonator and Pipe Assembly

Walker 55489 Exhaust Resonator and Pipe Assembly

Walker 55489 is an exhaust resonator and pipe assembly built to match original-system fit, sound, and flow characteristics. It is a direct replacement for select 2004-2005 Toyota RAV4 applications and uses an aluminized steel finish for added corrosion resistance.

For drivers searching for a 2004 Toyota RAV4 exhaust resonator and pipe assembly or a 2005 Toyota RAV4 OE-style exhaust replacement, this part number 55489 provides a factory-style solution with the correct inlet and outlet configuration.

Key Features

• Fits 2004-2005 Toyota RAV4, N/A
• Walker part number 55489
• Exhaust resonator and pipe assembly for OE-style replacement
• Steel body and steel pipe construction
• Aluminized finish for improved surface protection
• 1 inlet with pipe connection and 1 outlet with 2-bolt welded flange
• Overall length: 50 in.; resonator body length: 10 in.

Detailed Description

Walker 55489 is engineered for the 2004-2005 Toyota RAV4 to restore the original exhaust layout with a resonator and pipe assembly that follows OE-style dimensions and connection points. The 2.125-inch inlet, pipe-connection entry, and 2-bolt welded flange outlet help maintain the intended exhaust routing, while the round steel resonator body is tuned for controlled flow and factory-like sound characteristics. This part cross-references Monroe Shocks & Struts (e.g., 58574) for the same application.

Use this Walker 55489 exhaust resonator and pipe assembly when replacing a worn, rusted, or damaged section of the exhaust on a 2004 Toyota RAV4 or 2005 Toyota RAV4. The aluminized steel construction supports long-term service in demanding underbody conditions, and the OE-style design helps preserve the vehicle’s original exhaust tone.

What It Is Used For

• Replacing a corroded or damaged resonator and pipe section
• Restoring exhaust flow after a failed welded assembly
• Correcting exhaust noise caused by a leaking resonator body or pipe
• Addressing flange or connection damage at the outlet
• Returning a 2004-2005 Toyota RAV4 exhaust system to OE-style routing

Installation Notes and Tips

Verify the inlet diameter, outlet flange style, and overall length against the existing exhaust before installation. This application notes that if the original unit is welded in place, all required related parts should be replaced during service. Confirm the vehicle is a 2004-2005 Toyota RAV4 and match the exhaust layout to the existing system before final fitment.

Quality Assurance

Walker designs this resonator and pipe assembly to fit, perform, and sound like the original system, using tuning methods intended to deliver OE-style exhaust characteristics and consistent flow.
