  • Exhaust Gasket

  • Mr. Gasket 4805G - Mr. Gasket MLS Multi Layer S/S Header and Collector Gaskets

    Multi-Layered Steel (MLS) exhaust and header collector gaskets are designed for extreme cylinder pressures produced by high horsepower-high compression turbo-charged, supercharged and nitrous oxide engines.


  • Manufactured from three stainless steel layers, resists corrosion, will not burn through or push out and maintains maximum fastener torque retention
  • Stress formed inner and outer layer embossments act like springs that rebound under exhaust flange clamp load, creating force to seal excessive exhaust pressure produced from cylinder heads
  • Withstands different combinations of cylinder head (aluminum) and exhaust header or manifold (steel) materials, will not deteriorate from scrubbing action caused by different expansion rates in aluminum and steel material
