Step 1:  Properly support your stock exhaust system, and remove your stock exhaust up to the catalytic converter from the rear of your truck, working your way forward. Take caution not to damage the factory hardware and isolation mounts. (It is recommended to not fully tighten the clamps until the entire system has been installed.)

Step 2: For faster installation spread the pieces of the exhaust alongside of your vehicle according to the diagram shown.

Step 3: Start by placing clip-on nuts into frame, as shown on (Figure A). The clip-on nuts should slide right in hassle free.
