I'm currently getting a plan together for redoing my exhaust from manifolds to my muffler, my initial idea is to use a merge collector that has 2 1/4" inlets from each manifold to a 3" outlet. My current setup is a walker y pipe and it's too poorly put together to make modifying it worth it. My EFI manifolds have been cleaned up on all the runners and the outlets have been opened up to 2" outlets. If 2 1/4 pipe isnt ideal I'd like to hear suggestions.
