F150 4" Cat Back

Truck has a nice deep sound, turbos can breath now. Muffler could have been about an inch further forward so that the back hanger rod would stick all the way through the rubber mount in the hanger. As it is, the rod is flush with the rubber insert. It works as is, just a personal preference. Install was relatively easy, definately recommend having a second set of hands to help out.
