    a 3 inch hole in the baffle of a stock box will net you about 10 rpm....yes 10 rpm....not really worth the effort unless you want every rpm possible. we have done this multiple times and its usually 10 rpm max gain ( P.E.T. Tach ) I just did one a few months ago for a GP1800 and he gained, you guessed it, 10 rpm !
