So anyways I was wandering what you all thought my next mod should be on my gtp. I got what I believe to be a 3.4 not 100% sure kinda did some measuring but kinda hard to do without taking the belt off. And a cold air intake. The kid before me cut all the mufflers off so I gotta put some mufflers on it. But I'm wanting to drop pulley sizes(just one or two more) and I was wandering what next move should be? Headers?
