Default Factory captains call exhaust flaps issue
New to Mariahs and this site. Hello everyone!

I noticed while at the lake yesterday, that one of the shutter / flaps in the exhaust was all the way at the opening of the exhaust tip. I can feel the flap in the other exhaust about 6" up or so. I'm not sure how the system works or how/where this flap attaches. Any help would be very welcome.

Thanks!

    Correct, the flappers are designed to prevent water from backing up and getting into the exhaust manifold such as when you come off a plane.

    They are mounted in the exhaust down tube. Little square notches in the tube accept the flappers axel. See link for photo.
