Headers for 454
I have a 27′ Checkmate with a 454 Magnum MPI. Currently, the exhaust is stock MerCruiser cast iron manifolds and risers. The boat is also equipped with the Corsa Captain’s Call switchable system that diverts the exhaust through the propeller hub when activated. I need to keep the ability to silence the engine. I was planning on doing some upgrades to the engine soon with a more aggressive camshaft profile that is similar to what is used in the Mercury Racing 525EFI.
I have been told that my stock exhaust system will hinder performance and their use may result in exhaust water reversion with the increased cam duration.
I was considering the CMI part number 13186, but l need to know if they can be installed in conjunction with my current Captain’s Call system. If not, what system will work?
