Walker 53956 Exhaust Resonator and Pipe Assembly
Walker 53956 Exhaust Resonator Assembly
Walker 53956 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 pipe connection outlet, and aluminized steel construction to match the layout of the original exhaust on select Subaru applications.
Compatible With 2006-2009 Subaru B9 Tribeca and Subaru Tribeca models, this resonator assembly is engineered around the factory exhaust configuration for direct replacement service. The Walker 53956 part number is also referenced as SU2405 for the same application.

Product Details
Walker 53956 is built to follow the original exhaust system layout on 2006-2007 Subaru B9 Tribeca and 2008-2009 Subaru Tribeca models. The resonator is tuned to support factory-style exhaust tone while maintaining the flow characteristics expected from an OE replacement part. Its aluminized finish helps protect the steel construction, and the welded flange inlet supports a secure connection at the factory mounting point.
Use Walker 53956 when replacing a worn, rusted, or damaged resonator section on the Subaru B9 Tribeca or Subaru Tribeca. The assembly dimensions, inlet style, and outlet sizing are specified to align with the original exhaust routing and connection points.
Common Repair Uses
- Restores a damaged or corroded resonator section
- Addresses exhaust noise from a leaking resonator or pipe assembly
- Replaces a bent or rusted exhaust pipe section
- Returns factory-style exhaust tone on Subaru Tribeca applications
- Corrects fitment issues caused by deterioration of the original welded assembly
Installation Notes
Fits 2006-2007 Subaru B9 Tribeca and 2008-2009 Subaru Tribeca. If the vehicle uses a welded assembly, replace all required parts as noted in the fitment data. Verify flange style, outlet diameter, and overall length before installation to confirm alignment with the existing exhaust system. Professional exhaust installation is recommended for welded or flange-connected assemblies.
Quality Assurance
Walker designs this resonator assembly to fit, perform, and sound like the original system, using precise tuning methods to support OE-style exhaust characteristics. The aluminized steel construction and application-specific dimensions reflect a replacement part built for factory-style service on select Subaru models.
