Yep. We did mine in the Lee's parking lot at Muncie. I got the duals, so it took a little playing to line up the drivers side, but nothing bad. It fits right around the stock spare, and one thing to watch is the vent lines and a brake line off the diff may touch, so tie wrap them up out of the way. The stock clamps are junk, one broke while tightening, so I went with the steel band clamps, $6 each at a truck shop. They had nice shiny chrome ones, so they match well.
Oh, just remembered, don't let the sawsall get too far away. I had to cut about a 3" piece out of the long line to get it to fit. Better than being short. If you have the short bed, it will be more than that. Overall, great system. I ran their muffler with nothing else, no aeroturbine, or anything. Sounds great and no drone, barely louder than the stock, but with a deeper rumble. Until you get into it hard, then it roars, like a straight pipe. But at cruise, you will like it.
