Yes stock the Z does have two headers lol. comes into a y-pipe and then to the muffler which has two exhaust tips.Help me understand? So does the Z come with a header on each side of the motor then run into one collection pipe down to the back and then split out of the muffler? I might have seen a picture of this, but not sure? I just want to make sure I can put true duals on it once I get it. Thank you for helping!
