Walker 31600 Exhaust Pipe Flange Gasket

Walker 31600 Exhaust Pipe Flange Gasket

Walker 31600 is an exhaust pipe flange gasket built for sealing OE-style exhaust connections where a donut gasket is required. It uses high temperature graphite with a wire mesh core to help maintain a tight seal at the flange joint in Subaru, Toyota, Scion, Lexus, Mitsubishi, Buick, Chevrolet, Oldsmobile, and Pontiac applications.

Use this gasket for direct-fit exhaust repair work on vehicles such as the Subaru Forester, Subaru WRX, and Toyota Corolla when the original flange seal is worn, leaking, or damaged. The 31600 part number is also a common reference for repair planning and parts lookup.

Key Features

• Donut-style exhaust pipe flange gasket
• Inside diameter: 2.375 in.
• Outside diameter: 3 in.
• Thickness: 0.68 in.
• High temperature graphite construction with wire mesh core
• Works with OE exhaust components and Walker aftermarket replacement parts

Detailed Description

Walker 31600 is designed for exhaust flange sealing at converter-to-resonator, resonator-to-muffler, and related pipe junctions listed in the fitment data. The graphite sealing material and wire mesh reinforcement are selected for high-heat exhaust service, helping the gasket conform at the joint and maintain sealing performance under thermal cycling. This makes it a practical choice for repairs on Subaru Forester rear converter to resonator connections, Subaru WRX exhaust joints, and other listed applications where a donut gasket is specified.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Exhaust leaks at a flange or donut-style joint
• Noise from a failing converter-to-resonator connection
• Soot marks or odor from a leaking exhaust seal
• Vibration or rattling caused by a poor sealing surface
• Service issues after replacing exhaust components on listed vehicles

Installation Notes and Tips

Confirm the gasket dimensions and flange style before installation. Clean both sealing surfaces thoroughly, inspect the mating flanges for warping or corrosion, and verify the exhaust alignment before tightening the joint. For best results, match the gasket to the exact position listed for your vehicle, such as converter to resonator assembly or resonator assembly to muffler.

Compatible With select Subaru Forester, Subaru WRX, Subaru Crosstrek, Subaru Impreza, Toyota Corolla, Toyota Matrix, Lexus RX350, Scion xB, Scion tC, Mitsubishi Endeavor, Buick Century, Chevrolet Lumina, and other listed applications by year and exhaust position.
