Calling all EFI/MPI guys
 

I am ready to install my new Merc 383 MPI motor. I have Revolution exhaust lying around, and I would like to know what you all think about using them versus the included stock exhaust.

My primary concern is if they are different enough to require a remap, or to cause any problems without a remap.

Thanks in advance

I dont belive they will flow that much better than the factory set up. So a map should not be required, unless you have done other hard mods.. :) Jamie / Lakeside

Thanks,

I decided to stick with the stockers, at least until the warranty is up.

I may change my mind once I try to install the exhaust pipe/hose, it is TONS easier with the Revolutions. You can assemble the hose and riser, and slip it on the manifolds as an entire assembly.

The stock?????
