Product Details

Walker 31577 is an exhaust pipe flange gasket designed to complete exhaust repairs at the joint between exhaust sections. The donut profile helps create a secure seal where the pipe connection needs to stay tight under heat and vibration. Its graphite construction with a wire mesh core is selected for exhaust environments where temperature resistance and sealing consistency matter. This part number 31577 is listed for applications including 2019-2022 Toyota Corolla, plus select Toyota Matrix, Toyota Echo, Toyota Tercel, Scion xA, Scion xB, and Pontiac Vibe exhaust connections.

This part cross-references BRExhaust 256-1004 for the same application.

Common Repair Uses

• Exhaust leak at a flange or donut-style joint
• Noise from a worn sealing surface between exhaust sections
• Loss of seal at resonator-to-muffler or converter-to-muffler connections
• Replacement during exhaust pipe, resonator, or muffler service
• Restoring a tight seal on select Toyota Corolla exhaust repairs

Installation Notes

• Verify the gasket dimensions match the pipe and flange before installation.
• Clean mating surfaces thoroughly so the gasket seats evenly.
• Confirm the vehicle-specific position, such as resonator assembly to muffler assembly or converter to muffler, before ordering.
• Use the confirmed fitment for your exact year, make, and model; this part number 31577 is listed for multiple exhaust joint locations.
