Fits 2011-2016 Toyota Sienna, N/A. This part number is 56276.

Key Features

• Exhaust resonator and pipe assembly for OE-style replacement
• Precise tuning technology for controlled exhaust sound
• Steel body and pipe construction
• Aluminized finish for added corrosion resistance
• 2-bolt welded flange inlet and outlet for secure connection
• Round resonator body with 24.25-inch body length

Detailed Description

Walker 56276 is built for drivers replacing a worn exhaust resonator and pipe assembly on a Toyota Sienna. The design follows the original system’s fit and sound profile, with tuning focused on maintaining smooth exhaust flow and an OE-style tone. The steel construction and aluminized finish add durability for exhaust environments, while the welded 2-bolt flange connections support a straightforward exhaust repair. The part number 56276 is the reference to use when matching this assembly for the listed Toyota Sienna fitment.

This part cross-references AP Exhaust 68537 for the same application.

What It Helps Address

• Exhaust noise that has become louder or harsher than stock
• Corrosion or rust damage in the resonator and pipe section
• Leaks at flange connections in the exhaust system
• Reduced exhaust flow from a damaged or restricted assembly

Installation Notes

Verify the vehicle application before installation and compare the inlet and outlet flange style, overall length, and body dimensions to the original assembly. This Walker resonator and pipe assembly uses 2-bolt welded flange connections at both ends, so the existing exhaust layout must match the listed configuration. Confirm fitment against the vehicle’s exhaust routing and mounting points before final installation.

Quality Assurance

Walker designs resonators to fit, perform, and sound like the original system, with tuning focused on OE-style exhaust characteristics.
