Mr. Gasket MLS Exhaust Collector Gaskets

Mr. Gasket Multi-Layer Steel (MLS) Exhaust Collector Gaskets deliver professional-grade sealing performance engineered for the demands of high-performance exhaust systems. Built to handle the extreme cylinder pressures and thermal stress generated by high-horsepower, high-compression, turbocharged, supercharged, and nitrous oxide applications, these gaskets provide the dependability that serious performance builds require.

Advanced Multi-Layer Steel Construction:

• Three-layer stainless steel design provides maximum durability and long-term corrosion resistance
• Stress-formed embossments on inner and outer layers create a spring-like sealing action under clamp load
• Embossments rebound under exhaust flange load to maintain consistent, leak-free seal pressure over time
• Superior fastener torque retention resists loosening caused by thermal cycling and vibration

Performance Advantages:

• Resists burn-through and blow-out under extreme heat and exhaust pressure
• Eliminates exhaust leaks at critical header collector-to-exhaust connections
• Engineered to withstand the thermal stress of forced induction and power-adder applications
• Reusable construction allows for multiple installations when properly maintained

Mr. Gasket MLS Exhaust Collector Gaskets are a meaningful upgrade over traditional single-layer or basic composite alternatives, delivering superior sealing integrity where header collectors meet exhaust system components. Available in multiple configurations to suit a wide range of collector outlets and exhaust setups, they are the trusted choice for race engines, street performance builds, and any demanding application where exhaust reliability is non-negotiable.
