    Just get a Riva D-Plate and jetworks kit. Tripple pipes won't work on EFI's right now since there is no ECU. Also the freeflow will slow you down.

    Get with WFO. He is in your back yard and is the man with the EFI boats. I hear he has a cool set of tools too.

    Freeflow exhaust will require a ECU, as it leans out the engine

    I am not sure about that. It reduces back pressure at peak RPM

    Could somebody post a pic of the freeflow and a pic of the piece it replaces as I have a box of stock parts and have no idea what I'm looking for. Donald
