    No big deal. With lowered trucks, sometimes u have to. I have a nbs but it really doesn't matter what truck ur running. Just make sure ur suspension is at full droop when u build it, so ur sure u have clearance at all times.

    I work at a muffler shop, i dont recommend it. Because when you go over a bump, you axle goes up, and that exhaust will be mighty low. I would recommend dumping before the axle, i just did a bagged truck and dumped it, we thought about going under the axle, but no, wouldn't work. But hey, its your truck. Your call.

    I just don't recommend it, plus I'm in Colorado. The streets are so bad I'm sick of it, I'm raising my truck back up and going prerunner style instead.
