Is it time to replace the leaking exhaust flange gasket to restore proper exhaust sealing? The MAHLE Exhaust Pipe Flange Gasket is an OE-style replacement designed to create a tight seal between exhaust pipe flange connections. When exhaust components are removed for service or modification, the original gasket can become crushed, brittle, or heat-damaged, allowing exhaust gases to escape at the flange joint. Installing a new MAHLE gasket restores a proper seal, helping maintain correct exhaust flow, reduce exhaust noise, and prevent leaks that can affect performance or emissions. This gasket is commonly used on GM 6.6L Duramax engines, making it an ideal replacement during exhaust system repairs.

Manufactured to meet or exceed OE specifications, the MAHLE F31897 features a graphite-style flange gasket design engineered to handle extreme exhaust temperatures, pressure pulses, and vibration. Precision-cut construction ensures accurate alignment between mating flanges while maintaining consistent sealing pressure once the bolts are torqued to specification. MAHLE sealing components are widely trusted by professional technicians and engine builders for dependable durability, making this gasket a reliable choice whenever an exhaust flange connection is disassembled.
