The Story

Are you repairing an exhaust leak between the exhaust manifold and the up-pipe on your Duramax? The MAHLE Exhaust Flange Gasket is an OE-style replacement designed to create a tight seal between the exhaust manifold and up-pipe connection. When the original gasket is damaged by heat cycles, vibration, or exhaust pressure, leaks can develop, causing ticking noises, reduced turbo efficiency, and a loss of exhaust energy. Installing this precision-fit gasket restores proper exhaust sealing and helps maintain optimal exhaust flow and turbocharger performance on GM 6.6L Duramax engines.

Manufactured to meet or exceed original equipment standards, the MAHLE F31903 features a durable beaded steel gasket construction that withstands extreme exhaust temperatures and pressure fluctuations. Precision stamping ensures consistent sealing pressure between mating surfaces while resisting distortion during repeated heat cycles. Built with OE-grade materials and engineering, MAHLE gaskets deliver dependable durability and long service life, making them a trusted choice for professional diesel technicians and engine builders.
