    Banana CMI Exaust on 288 496HO

    Has any one installed a set of CMI Headers on a 496HO? If so did you gain any MPH. I was told by the guys at Trick Marine that they have been told they were getting 4-5 MPH after installing them. I would hate to spend $4,000. just to make more noise.

    Re: CMI Exaust on 288 496HO

    I have been seriously considering the same thing, but for 4K... man!. A little more and you can add a raylar kit for guaranteed 525.

    I was in a run with a guy who added them to his 32 Dominator with twin HO's and the boat was fast, said he gained 4-5 out of it, but im don't know of anyone with a single HO sun that has tried it.

    Hopefully someone will chime in.
