Cometic Gasket MLS Exhaust Manifold and Header Gaskets

2006–2025 Chrysler / Dodge / Jeep / Ram 6.1L SRT8, 6.4L 392, 6.2L Hellcat

C5872-030-6.1L

Overview:

The Cometic Gasket MLS Exhaust Manifold and Header Gaskets are engineered to meet the demanding needs of high-performance Chrysler, Dodge, Jeep, and Ram vehicles equipped with 6.1L SRT8, 6.4L 392, and 6.2L Hellcat engines from 2006 through 2025. Designed for extreme cylinder pressures, these multi-layer steel (MLS) gaskets provide a reliable seal between the exhaust manifold or headers and the cylinder head, ensuring optimal exhaust flow and preventing leaks under the most rigorous driving conditions.

Ideal for enthusiasts and professional builders alike, these gaskets are the top recommendation for use with quality aftermarket header systems, delivering durability and consistent performance without the need for additional sealants.

Key Features:

Cometic MLS Exhaust Gaskets combine advanced materials and precision engineering to offer superior sealing and longevity. Key features include:

• Multi-Layer Steel (MLS) construction designed to withstand extreme cylinder pressures
• Maintains torque set to prevent gasket push-out and blowouts
• Corrosion-resistant materials for extended service life
• Compatible with various combinations of cylinder head and exhaust manifold materials
• No sealants required for installation, simplifying the process
• Compressed thickness of 0.03 inches for a precise fit
• D-shaped port design measuring 2.082 x 1.508 inches for optimal exhaust flow
• Engineered specifically for high-performance HEMI engines including SRT8, 392, and Hellcat variants

Construction & Design:

These gaskets feature an uncoated multi-layer steel (MLS) design that provides exceptional strength and flexibility. The layered steel construction allows the gasket to conform to surface irregularities while maintaining a robust seal under thermal cycling and high exhaust gas pressures. The corrosion-resistant properties ensure durability even in harsh operating environments, preventing premature failure common with conventional gasket materials.

The D-shaped port profile is optimized to match the exhaust manifold and header ports, promoting efficient exhaust gas evacuation and reducing backpressure. This precise engineering supports improved engine performance and longevity.

Installation & Fitment:

Installation of Cometic MLS Exhaust Manifold and Header Gaskets is straightforward and requires no additional sealants, making it an ideal choice for both professional mechanics and experienced enthusiasts. These gaskets are designed to fit perfectly with factory and aftermarket exhaust manifolds and headers on the specified Chrysler, Dodge, Jeep, and Ram models.

Ensure proper torque specifications are followed during installation to maintain the gasket’s sealing integrity and prevent exhaust leaks. The gaskets are compatible with the following vehicles:

• 2006–2024 Chrysler 300 6.1L SRT8 & 6.4L 392
• 2008–2023 Dodge Challenger 6.1L SRT8, 6.4L 392, 6.2L Hellcat
