    I say build your own. I got Pacesetters, and Magnaflow spun cats (the angled ones to go up and over the crossmember) some mandrel bends, and some pipe. (and two 3" and five 2 1/2" band clamps) Made the X out of two 180* u-bends. Remember you'll have to re-bend your tranny lines

    The one thing about running no cats is to make sure you have good mufflers. The headers, a CAI, and no cats = LOUD.

    This is my first exhaust job, by the way. And I learned how to weld 9 months ago (I'm hooked)
