Walker 47812 Exhaust Resonator and Pipe Assembly

Overview

Walker 47812 is an exhaust resonator and pipe assembly built to match original-system fit, sound, and flow characteristics. It uses tuned resonator design and OE-style acoustics for a direct replacement on select applications.

Key Features

• Steel body and steel pipe construction for exhaust system durability
• Aluminized finish for added corrosion resistance
• Round resonator body with 18-inch body length
• 2-bolt welded flange inlet and outlet connections
• Overall length of 81.75 inches for application-specific fitment

Detailed Description

This Walker exhaust resonator and pipe assembly, part number 47812, is engineered for vehicles that need original-style exhaust tone and flow. The resonator uses precise tuning to help maintain OE sound characteristics while supporting efficient exhaust movement through the system. It is a fitment-based replacement for the Mazda 6 and is listed for 2003-2008 Mazda 6 models, except Super Ultra Low Emission Vehicle (SULEV) applications. This part cross-references AP Exhaust 78258 and BRExhaust 288-105 for the same application.

What It Is Used For

• Replacing a worn or damaged exhaust resonator and pipe assembly
• Restoring factory-like exhaust sound after system wear
• Addressing exhaust flow restriction caused by internal deterioration
• Correcting flange or pipe section damage in the exhaust path

Installation Notes and Tips

Verify the vehicle is a 2003-2008 Mazda 6 before ordering, and confirm the application is not a SULEV model. Match the 2-bolt welded flange connections and overall length to the existing exhaust layout. Professional installation is recommended to ensure proper alignment and sealing.

Quality Assurance

Walker designs resonators to fit, perform, and sound like the original system, with tuning focused on OE-style sound and flow characteristics.
