Construction & Design

The gasket set features a multi-layer steel design, combining thin layers of stainless steel with a proprietary sealing material to withstand extreme heat and pressure typical of high-performance exhaust systems. This construction ensures the gasket maintains its integrity over time, resisting warping and degradation caused by thermal expansion and contraction cycles.

Each gasket is precision-cut to match OEM specifications, guaranteeing a perfect fit and optimal sealing surface. The design eliminates the need for additional sealants, reducing installation time and potential for errors. This robust engineering makes the Cometic MLS gasket set ideal for both factory replacement and performance upgrades.
