    Manufacturer's Part Number:
    4805G

    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

    Rated 5 out of 5 by from Positive seal Noticed that I had a small leak at the header gasket on my 99 C5 Vette. A couple of the header bolts had lost torque. I decided to go with Mr. Gasket MLS header gaskets and Stage 8 locker bolts so I would not have a "repeat". I'm very satisfied with the result and continue to be a loyal customer of Mr. Gasket products. The Stage 8 fasteners went on a lot easier than I had anticipated and I look forward to a "permanent" seal. :)
