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?

If it was up to me I would remove the sensors and replace them with resistors

The catalyst eliminator covered that part on the post O2 sensors. I still have the pre sensors.
