    5.0 MPI Mercruiser, w/Bravo III Drive, Alum Manifolds, 6" SS risers, max volt CAT eliminator
    Has any one replaced the pot metal manifolds, risers with Aluminum manifolds and Stainless Steel risers? In addition adding the Volt Max brand catalyst eliminator. If so has it been a success or an issue?
