Hi everyone...
I am doing some exhaust work on my GT-21. I am curious if people think exhaust flappers are important. I have Stainless Marine manifolds with custom risers so they have a nice amount of lift above the water line. I also have GIL clamp on mufflers with lots of baffles. I have to change exhaust tips and I have a used set with internal flappers in fair condition. I am also concerned if the tips have enough extension for the mufflers to grab onto (1 1/2") but that is another story...
I am thinking they good enough to stop a large surge of water, but I have to believe the riser and muffler help too. As I looked at exhause tips I realized many tips do not have flappers. Who uses the tips without flappers?
Am I being overly concerned? My exhaust tips are rigth at the water line... thanks in advance for all your replies!
