i wanted to take my cats out will i lose any power or gain or should i juat leave them in
Generally less restriction equals more power, but you will be making your vehicle illegal to drive on the street. I would not do it, instead look at the exhaust system that flipside has posted about. It looks promising and keeps the car street legal for those quick trips to the store.:cool:
