    Looks great!

    Are those the IMCO removable mufflers? I head they work well but impede a lil horsepower so they're not very common on big Hp boats.

    Not IMCO's. They look like Zoomers. We used them in the past. The "propeller" is restrictive and costs HP. We've removed them and made gains, but increases the noise level quite a bit. The IMCO mufflers are way less restrictive.

    Thanks for the info. Have you compared them on the dyno?

    I have not as it would be almost impossible to duplicate the exhaust, load, etc. as installed in a boat. I did a comparison on the lake. Zoomers with "propeller" 5300 rpm's, without "propellers" 5500, IMCO Gatlins 5625, no mufflers 5800. 540 BBC EFI 725 HP @ 6000

    Edit: I went back and looked at the results and changed a few numbers. Not sure if I was able to delete the first post if it shows up twice.
    Nice thanks for the info.

    Are you the first guy to actually have muffler bearings for the fans in the exhaust?
