Detailed Description
Walker 53990 uses precise tuning technology to deliver exhaust flow characteristics and sound that follow the original system profile. The resonator body is made from steel with an aluminized finish, and the pipe assembly uses a 2-inch inlet inside diameter and a 2.5-inch outlet outside diameter. This part cross-references GM 22751826 and 23452801 for the same application. For buyers searching for a Buick Enclave exhaust resonator or GMC Acadia resonator and pipe assembly, this part number 53990 provides a fit-focused replacement option.
What It Helps Address
- Exhaust resonance or drone from a worn resonator assembly
- Corrosion-related failure in the exhaust pipe or body
- Factory exhaust sound that no longer matches original tuning
- Fitment issues on a damaged or previously repaired exhaust section
Installation Notes
Fits 2013-2017 Buick Enclave, right. Fits 2013-2016 GMC Acadia, right, with dual exhaust; if the assembly is welded in place, replace all required parts. Verify inlet and outlet dimensions, routing, and right-side application before installation. Part number 53990 should be matched to the vehicle’s exhaust configuration before service begins.
Quality Assurance
Walker resonators are engineered with tuning methods that target OE-style sound and flow behavior, making 53990 a practical replacement for original-equipment service needs.
