8.2MAG and 8.2HO Mercruiser NON-Catalyst Exhaust Header System

The header system is slightly taller than the restrictive factory system due to the improved collector design and down slope. This new header system features a pre-catalyst sensor port provision and NO post cat sensor provision as this header is designed for use with the Cat-Eliminator test system. The headers will connect directly to the factory wet exhaust exhaust hose connection. The header system is available in Satin or Production polished versions. These headers stand 3-1/4" taller than the top of the engine
