I did mine early last spring and noticed nothing significant other than a tad bit louder. Of course my caveat is that i see very little lake-like smooth weater to really get a solid bead on 1 or 1.5 mile per hour gains.
It is primarily a drip pan concept in areas where condensation periods are pevelant. The flip side it does open up roughly an inch or maybe two in diameter for the pipes to breath easier i.e. header concept. Mine were pretty clean after two seasons so they hadn't seen much condensation action prior to removal. I would suspect if you pulled yours and they were clobbered with rust or calcium buildup, then i would leave them. When I sell my plates will go with the boat for sure.
