I was wondering if the gibson super truck exhaust would be in the way if I tried to put my truck on a lift. Any help would be appriciated.

 

Shouldn't be a problem even on the "4 arm" type lifts (usually used for cars) as each arm's pad is adjustable vertically for height and the frame is pretty much same height as the bottom of the box panels. But usually they run pickups onto 4 post ramp lifts.

Don't think you'll have any troubles. Otherwise the f150 L guys would be screaming too.... ground effects for worse clearance.
