I've had my 03 Z for about 3 months now. I was checking out the aluminum chassis reinforcement plate that A & A Corvette sells and it sounds like a good deal. However, laying down and peeking under my car with a flashlight, I do not see a stock plate where one is supposed to be???? My exhaust pipe diameters seem to hang slightly below the floorboard level where the plate should bolt up. Can this be true? My tailpipes are exposed all the way from the engine to the mufflers. Also the pipes appear to be kind of a rust color and I thought the Z had titanium pipes?
