I took care of one of my cats, and the other one is half dead(drilled out). I passed emissions with flying colors, and it seemed to make a little diffrence, not much though. There really isnt to big of a need to get rid of the cats. They are restrictive and all, but I dont know how much that actually hurt the truck.
what about 1 high flow cat to a turbo muffler and cut off the littlw whisle thingy? any one one dont this?
i know horse power isnt a big thing but im thinking with one cat and a turbo muffler being smaller it would help with ground clearence.
