Mr Gasket Exhaust Collector Gasket 4888G; 2.500"

Multi-Layered Steel (MLS) header collector gaskets are designed for extreme cylinder pressure 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.
