I've been reading some of the old threads and i can't figure out whether or not losing the cat will gain power. I want to do my exhaust but im not sure whether to change to a hi-flow or keep it stock. Some say yes and some say no..
By the way, 2.5inch piping should be fine for a gt right???
removing the cat will give you better air flow but it is illegal

let me see... do I wanna breathe clean air or do I want that 1 free hp? Seeing as you're from socal... I'd worry more about breathing.
