Multi-Layer Steel Exhaust / Header Gasket - sold as a single gasket, requires two pieces for one engine.

This is the factory replacement exhaust gasket for most V8 LSx engines since 1997, fits LS1, LS2, LS3, L76, and L92 applications. Not designed to fit the stock exhaust manifolds for the 2001 thru 2004 LS1 or LS6 Corvette - these applications use GM gasket #12576221.

The large round design of this #12617944 gasket will fit most aftermarket header applications and the GM stamped steel design provides excellent sealing capabilities for the most severe applications.
