Walker 48342 Exhaust Resonator and Pipe Assembly

Walker 48342 Exhaust Resonator Assembly

Walker 48342 is an exhaust resonator and pipe assembly built for OE-style fit, flow, and sound control. It is engineered with aluminized steel construction and welded 2-bolt flange connections to match the original exhaust layout on select Toyota Avalon models.

Compatible with 2005-2012 Toyota Avalon applications, this Walker resonator assembly supports a direct replacement path for drivers seeking factory-like exhaust tone and proper exhaust routing. The Walker 48342 part number is also referenced in cross applications for the same vehicle fitment.

Key Features

• Exhaust resonator and pipe assembly for select Toyota Avalon models
• Aluminized steel body and pipe construction for corrosion resistance
• Round resonator body with 22-inch body length
• Overall length: 86.5 inches
• 1 inlet and 2 outlets with 2-bolt welded flange connections
• Designed to deliver OE-style exhaust sound and flow characteristics
• Walker 48342 direct-fit replacement part

Detailed Description

Walker 48342 is designed for 2005-2012 Toyota Avalon vehicles and follows the original exhaust system layout with a resonator body and integrated pipe assembly. The steel construction and aluminized finish help support long-term exhaust service, while the tuned resonator design is intended to maintain factory-like sound characteristics and steady exhaust flow. If you are replacing a worn or damaged exhaust resonator on a Toyota Avalon, this assembly provides a direct-fit solution that aligns with OE-style dimensions and flange configuration. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Exhaust rattling or resonance from a damaged resonator
• Rust-through or corrosion in the resonator and pipe section
• Exhaust leaks at worn flange connections
• Unwanted exhaust tone changes after component failure
• Restricted exhaust flow caused by internal deterioration

Installation Notes and Tips

Verify the inlet and outlet flange style before installation to confirm match-up with the existing exhaust system. Compare overall length, body length, and outlet configuration against the removed part on your Toyota Avalon to ensure proper alignment. Professional installation is recommended for exhaust components that use welded flange connections, especially when replacing corroded hardware or mating surfaces.

Quality Assurance

Walker designs this resonator assembly to fit, perform, and sound like the original system, using tuning methods that support OE-style exhaust behavior. Walker 48342 is built as a direct replacement for select Toyota Avalon applications and is backed by Walker’s product engineering standards.
