Detailed Description
Walker 22144 is engineered as an exhaust resonator and pipe assembly for select Buick LaCrosse models. The design focuses on proper exhaust flow and sound control, using precise tuning to help maintain the original character of the exhaust system. With a steel body, aluminized finish, and OE-style configuration, this part supports a direct replacement for vehicles that require a resonator and pipe assembly in the exhaust path. This part cross-references GM OE numbers 13229567 and 13229571 for the same application.
The Walker resonator line is built around fit, flow, and sound consistency. For buyers replacing a worn or damaged exhaust resonator assembly, the 22144 provides a factory-style solution that aligns with the original system layout on Buick LaCrosse applications.
What It Is Used For
- Replacing a rusted or damaged exhaust resonator assembly
- Restoring OE-style exhaust tone after system wear
- Addressing exhaust leaks at the resonator and pipe section
- Maintaining proper exhaust flow through the mid-pipe area
Installation Notes
Fits 2014-2016 Buick LaCrosse, N/A. Fits 2010-2013 Buick LaCrosse, N/A. The 2010-2013 Buick LaCrosse note states that if the assembly is welded in place, all required related parts should be replaced during service. Verify inlet and outlet configuration, flange style, and overall length before installation. Professional exhaust service is recommended for welded applications.
Quality Assurance
Walker uses precise tuning technologies to deliver OE-style sound and flow characteristics in its resonator assemblies.
