    You need duals to have an x or h pipe.

    a y pipe would mean you'd stick with a catback. if you get an x or h you will need a true dual setup. I've heard that X pipes net more power, but H gives better sound.

    z pipe


    h/x pipes are for balancing different pressures between 1 and 2 banks. theres very little flow between them, air just kinda bounces back and forth between the two duals. imo, most x pipes are very restrictive at the x. save your money and go with an h for true duals.

    Where is your proof that an X-pipe is restrictive?

    None, hence the letters IMO

    But, I used to work in a custom exhaust shop and made them there. When you cut an oval in the side of pipe and join it, the area where the oval is(x joint) the circumference is smaller. We used to simply cut an oval and weld the two oval together. I've seen some manufactured x pipes that have a camber between the two pipes, which doesnt restrict the size of each pipe. I havent seen any dyno numbers comparing the two but cant imagine any more than 5% hp difference.

    The exhaust is supposed to follow the same path, not cross over. Meaning the driverside exhaust never crosses over to the right. It creates a low pressure area.
    and 15 horsepower is a big difference when you consider how much an X-pipe cost.
