Ordered this exhaust setup for deep throaty sound without being obnoxiously loud, especially in the cab. The sound, appearance, and easy installation was great! Even without having access to a lift. Height of 4x4 was enough to install laying on garage floor. Everything matched up perfectly. Great Product!

After receiving my Gibson Exhaust I laid them out on the grass beside my truck and everything was there. I then removed my old exhaust by unbolting the front end then I used a electric saw and cut the pipe in the center and removed it , I then followed the instructions to install the Gibsons , it took me about 3 hrs to install them buy myself. Please don't forget block your wheels and put 2 jack stands one under each side under the rear axecell before going under your truck.
