Detailed Description

The gasket’s perforated metal body, fiber core, and metal fire ring are specified to help maintain a secure seal at the exhaust joint where heat and vibration are common.

This part cross-references BRExhaust 256-193 for the same application. The 31646 gasket is a practical choice when replacing a leaking flange gasket during exhaust service on a Honda Civic or Acura EL, especially when matching OE-style exhaust components is important.

Common Repair Uses

  • Exhaust leak at the flange connection
  • Noise from a failing exhaust joint
  • Soot or residue around the exhaust flange
  • Loss of sealing after exhaust pipe service
  • Replacement of a worn gasket on a 1999-2000 Honda Civic or Acura EL

Installation Notes and Tips

Inspect the flange surfaces for warping, corrosion, or debris before installation. Clean both mating surfaces thoroughly so the gasket can seat evenly, and verify bolt hole spacing and port dimensions match the existing exhaust connection. Use the 3-bolt layout and the listed center-to-center measurements to confirm fit before assembly.

Quality Assurance

Walker designs this gasket for use with OE exhaust components and Walker aftermarket replacement parts, giving buyers a replacement option built around standard exhaust service requirements. Verify vehicle application by year, make, and model before ordering the Walker 31646 gasket.
