One word of advice to anyone attempting this without a lift: cut the original as close to the front of the muffler as possible. The shorter it is the easier it will be to get it past the differential and the crossmember in front of the rear axle. I cut mine where Pat showed in his photo but I had to raise the truck nearly two feet in the air to wiggle the pipe out. Other than that it was an easy install. Probably took about two hours by myself in my garage to remove the old and install the new. You definitely need a floor jack, jack stands and either a sawzall or air cut-off tool. Took longer to get the old stuff off than it did to install the new system.
