will my check engine light come on when i put my H pipe on in place of my old stock h pipe with cats? I know they sell that thing for your car to make it so the check engine light comes on but i dont want to spend $60 on that crud or whatever it is. Does the check engine light always come on or just sometimes aftre you change to a offroad H pipe?
