What would be the best sounding exhaust?

If money is no object, have dual exhaust installed with no mufflers; using the cats as mufflers. Use the same smaller diameter pipe all the way back except for the tips. Get two exhaust tips that are large diameter (3 1/2' or 4") and at least 1 1/2 feet long. They should exit about 3 feet apart (not next to each other). As my Dad used to say, "It will tickle your toes." If it turns out to be too loud, you can add gl pack mufflers slightly ahead of the center point between the engine and rear bumper. I have a 1991 Legend coupe, but my wife drives it and won't let me modify the exhaust. My 280 Z Datsun is going to get the treatment, though.
