I have true dual super 40's on my 96 with the 5.7L. (True duals, No cats, 2.5" Pipe from the manifolds back, dumped before the rear end). I think it sounds really good, and is not too load--but I like loud pipes. Also have the same setup on my '63 Nova SS with a 383 Stroker. With more horsepower they sound that much better IMO. I think you'll be pleasantly surprised!
