Walker 31601 Exhaust Pipe Flange Gasket - Converter To Resonator Assembly or Converter To Y-Pipe

Walker 31601 Exhaust Pipe Flange Gasket

Walker 31601 is an exhaust pipe flange gasket built for OE-style exhaust repairs where a secure seal is needed between mating exhaust components. It uses a fiber and metal laminate with a metal fire ring to help maintain sealing performance at the flange connection on supported Chevrolet, Buick, Oldsmobile, and Pontiac applications.

Compatible With 1990-2001 Chevrolet Lumina, Chevrolet Monte Carlo, Oldsmobile Cutlass Supreme, Buick Regal, and Pontiac Grand Prix exhaust connections at the converter to resonator assembly or converter to Y-pipe, depending on vehicle configuration. This part cross-references BRExhaust 256-1064 for the same application.

Detailed Description

Walker 31601 is engineered for exhaust flange sealing at the connection point between the converter and resonator assembly or the converter and Y-pipe, depending on the vehicle. The 4-bolt design and measured bolt spacing help support proper alignment during exhaust repair, while the laminate construction and metal fire ring provide a sealing surface suited to high-temperature exhaust flow. Use Walker 31601 when replacing a worn or leaking flange gasket on applications such as Chevrolet Lumina, Chevrolet Monte Carlo, Buick Regal, Oldsmobile Cutlass Supreme, and Pontiac Grand Prix.

Common Repair Uses

• Exhaust leak at a flange connection
• Noise from a damaged or deteriorated gasket
• Soot marks or odor near the converter-to-resonator joint
• Failed seal after exhaust component replacement
• Misalignment at a 4-bolt exhaust flange

Installation Notes and Tips

Confirm flange style, bolt pattern, port size, and bolt spacing before installation. Clean both mating surfaces thoroughly so the gasket seats evenly, and inspect the flange faces for warping, corrosion, or pitting that could affect sealing. Verify the application position on the vehicle, since supported fitments include converter to resonator assembly and converter to Y-pipe locations.

Quality Assurance

Walker supplies exhaust sealing components designed to work with OE exhaust parts and Walker replacement systems. The 31601 gasket is built to match the listed flange dimensions and application-specific fitment for direct exhaust repair use.
