What It Helps Address

  • Exhaust leaks at a flange connection

  • Soot or residue around the exhaust joint
  • Loss of sealing between exhaust pipe sections
  • Service replacement for damaged or compressed gasket material

Installation Notes and Tips

Confirm bolt hole count, bolt-to-bolt length, and inside diameter before installation. Match the gasket to the exact exhaust position shown for your vehicle, such as the Hyundai Sonata manifold converter to front pipe or the Kia Sportage flex pipe to rear converter connection. Inspect flange faces for corrosion, warping, or debris so the new gasket can seat evenly.
