the x/h pipe debate.
I want to buy an h or x pipe on my 97 GT but dont know which way to go. Maybe you guys can answer some of my ? First which will give me more power? What is the difference in sound? If I get an offroad, how do I make the check engine light go away? If I get one with cats, will the sound be different? Will the engine light still go off and will it pass smog with only 2 cats? Also, what brands do you guys recommend?
