Walker 22270 Exhaust Resonator and Pipe Assembly

Walker 22270 Exhaust Resonator Assembly

Walker 22270 is an exhaust resonator and pipe assembly built for OE-style fit, flow, and sound control. It uses a 2-bolt welded flange inlet, a 2-inch outlet outside diameter, and aluminized steel construction to match the needs of the exhaust system on select Nissan Altima models.

Compatible with 2007-2009 Nissan Altima applications, this resonator assembly is engineered to follow original-system tuning and help maintain factory-like exhaust tone. Walker 22270 is a direct-fit style replacement for drivers looking for a precise exhaust repair on the Nissan Altima.

Application Details

Walker 22270 is designed for 2007-2009 Nissan Altima, N/A. Fitment notes apply to vehicles built to 02/2009; if the exhaust uses a welded assembly, replace all required parts during service. This part cross-references AP Exhaust 48701 for the same application.

What This Part Helps Address

• Exhaust noise that has changed after resonator wear or damage
• Rust or corrosion in the resonator and pipe section
• Cracked or leaking exhaust joints at the flange connection
• Factory exhaust tone that has become louder or uneven
• Replacement needs on a 2007-2009 Nissan Altima exhaust system

Installation Notes and Tips

Confirm the inlet flange style, outlet diameter, and overall length before installation. Because this assembly uses a welded flange inlet and pipe connection outlet, verify the existing exhaust layout on the vehicle before ordering. For welded assemblies, replace all required related exhaust parts at the same time to avoid fitment issues and repeat labor.

Quality Assurance

Walker designs its resonators to match original-system fit, performance, and sound characteristics using precise tuning methods. The aluminized steel construction and OE-style configuration support a service replacement that follows factory exhaust design expectations for the Nissan Altima.
