I was always told you might lose up to 10 HP but have never seen any numbers. I have high flow cats and no cats on my 4th Gen and it did feel a little stronger but the cats made my neighors happier. They were glad I sold my Camaro. They asked my wife if my new car was going to be as loud. I say louder, maybe.

Good luck with your new car.
