Angry No Cats question.

If I were to remove the cats would it help out any?? I was told that the cats are extremely constrictive and well I'm pretty damn disappointed in this car hitting 13.6 all the damn time

Stock cats I can see being alittle restrictive. A nice aftermarket quality cat won't be. I watched a guy dyno 2RWHP difference between cats and no cats on a highly modded car.
