BBC TRS and Bravo exhaust hole dimension?
 

Does anyone know what the standard dimensions for where the exhaust holes exit the boat on a normal Bravo and TRS setup for a BBC? I ask because I have a set of Gil dry tail pipes that came with a used set of manifolds that I can not use. They are the 4 1/2 inch size and seem to exit higher then my 4 inch dry tails that I already had for my standard Bravo setup. The following picture shows my old tail pipe next to the ones I just picked up. In the picture the one that I just picked up the flange is almost flat on the ground and my old one the back of the flange is quite a bit off the ground.
