    go over the cross member, unless you wanna pick it up off the ground.

    ive seen a few both places, its easier to put it in front of the axle. if can still be ripped off in both places, depends on what you do. i have mine end about 2' infront of the axle straight back.

    I want to do a dual exhaust on my rig one day, and I was thinking I might just have both my pipes routed down the left side of the transmission cross member, and have both exit on the left side in front of the rear tires. NASCAR routes their exhaust systems this way.

    One reason I would not want an exhaust pipe to be routed on the right side of the transmission cross member and transfer case, on a GM 4X4, is because the exhaust pipe would be too close to the transfer case and heat it up, plus it would take some tight bends to route it around a transfer case.

    I would definitely say over the crossmember no matter what. And also, instead of in front of or behind the rear tire. Just keep it tucked up inbetween the frame rails and have it dump with a turn down in front of the rear axle on either side of the diff. I would say about 8 inches before the ubolts, and still tucked up high to be safe.
