A great performance upgrade for stock engines. These systems are a direct replacement for stock Mercruiser manifolds in Bravo and Alpha applications where the exhaust outlets exit through the transom in the stock location. They will also work with EMI Silent Select or other aftermarket selector systems as well as stock Merc "S" pipes. Brackets to keep all of the stock components in their existing locations (shift quadrant, ignition module and oil filter bracket) are included (There is an additional charge on some late model EFI systems). Standard with black Fusioncoated finish-optional finishes are available. Specify the correct accessory brackets and options when ordering. Not for use with engines equipped with High Performance camshafts! System for Big Block Chevy System includes 1pr EMI Thunder Exhaust Manifolds, 1pr. aluminum risers, bolts, gaskets, fittings and accessory brackets (specify when ordering)
