What's really baffling is that we also later installed a set of the Pypes Tri-Y headers on the car which eliminated the cats. I thought the car was going to be dreadfully loud and it barely got any louder. It defies everything we've ever tested exhaust on.

its usually the cam change that really wakes up the exhaust sound on these cars, in my experiences with LS powered cars
