Exhaust Gasket Manifold Set GM LS 97-15

The Exhaust Gasket Manifold Set GM LS 97-15 from MAHLE ORIGINAL/CLEVITE (MS16124) is a precision multi-layer steel gasket kit engineered for GM LS-series engines spanning 1997 to 2015 model years. This OEM-specification component seals the exhaust header or manifold interface with 1.868-inch round port geometry, preventing exhaust leaks that compromise engine efficiency and create unwanted noise under load. Built to original equipment standards, this gasket set maintains critical pressure sealing across temperature cycling and high-heat cycles common to performance and stock engine builds alike.

The multi-layer steel construction delivers durability across repeated heat cycles without degradation or blowout. Unlike single-layer gaskets, this design distributes clamping load evenly across the 1.868-inch round ports, reducing the risk of localized hot spots and gasket failure. The kit format provides everything needed for complete header or manifold gasket replacement, eliminating the need to source components individually. At 0.52 lbs and compact dimensions (6.15 x 0.4 x 23.1 inches), the set fits standard packaging and installation geometry across the full LS engine family, whether in trucks, SUVs, or performance applications.

This gasket set is ideal for owners rebuilding exhaust systems, replacing worn or failed header gaskets, or performing preventative maintenance on aging LS-powered vehicles. Technicians and DIY builders doing header installation, manifold repair, or engine-out service will find this kit essential for proper sealing without custom fabrication. MAHLE ORIGINAL and CLEVITE are recognized OEM and aftermarket suppliers trusted across the automotive service industry, ensuring this gasket meets specification-level quality expectations. Whether rebuilding stock exhaust systems or upgrading to performance headers, this LS gasket kit provides the sealing integrity needed to prevent exhaust intrusion and maintain engine performance.
