Walker 22265 Exhaust Resonator and Pipe Assembly

Walker 22265 is an exhaust resonator and pipe assembly built with steel construction and an aluminized finish for OE-style replacement needs. It is tuned to deliver the flow characteristics and sound profile expected from the original system on select Nissan Altima applications.

Compatible With 2007-2008 Nissan Altima and 2009 Nissan Altima built before 01/2009, including optional parts for split system applications.

Key Features

• Steel pipe and body construction for exhaust system durability
• Aluminized finish for added corrosion resistance
• Round resonator body with 22-inch body length
• 33-inch overall length for direct replacement packaging
• 2-bolt welded flange inlet for secure exhaust connection
• Single pipe outlet with 2-inch outside diameter
• OE-style tuning for flow and sound characteristics

Detailed Description

This Walker exhaust resonator and pipe assembly, part number 22265, is engineered as an OE-style replacement for select Nissan Altima models. Walker uses precise tuning methods to help the exhaust system maintain original sound characteristics while supporting proper exhaust flow. The steel body, steel pipe material, and aluminized finish are specified for everyday underbody use, while the round resonator design and welded flange inlet support a factory-style fit.

This part cross-references Nissan 20300JA000 for the same application. For buyers searching for a 2007-2008 Nissan Altima exhaust resonator and pipe assembly or a 2009 Nissan Altima resonator before 01/2009, Walker 22265 provides a direct-fit replacement option.

What It Helps Address

• Exhaust noise that no longer matches the original sound profile
• Damaged or rusted resonator and pipe sections
• Restricted exhaust flow caused by worn internal components
• Fitment issues from replacing a factory-style resonator assembly
• Corrosion-related exhaust leaks in the resonator section

Installation Notes and Tips

Verify vehicle build date before ordering, since 2009 Nissan Altima coverage applies only to vehicles built before 01/2009. Confirm the 2-bolt welded flange inlet and 2-inch outlet connection match the existing exhaust layout before installation. This part is listed for N/A position fitment and is intended for split system applications where noted.

Quality Assurance

Walker designs this resonator to fit, perform, and sound like the original system, using tuning methods aimed at OE-style exhaust behavior. Part number 22265 is built to match the specified application details for select Nissan Altima models.
