08. This shot of the tech fastening a header bolt shows that for do it yourselfers, there's enough room to make it worth considering installing it yourself. You can also see the heatshielding.

09. Banks' headers have what the company calls the "PowerPickle" high-velocity pulse converter. It's a lobe in the center of the merge collector that helps generate low pressure in the tubes, which helps remove exhaust to increase torque. They are constructed with 0.625-inch-thick flanges welded 360 degrees on both sides for a long-lasting seal.

10. All the fabrication of the exhaust system is OE-quality. Check out how well the headers and exhaust fit.

11. The Y-pipe merge area also shows the high quality of the bends and welding. In our opinion,the equipment is better than OE.

12. Installing the polished-stainless 4-inch tailpipe tip is the finishing touch on the exhaust installation. The Dynaflow muffler produces an exhaust sound that's authoritative, yet civilized.

13. Installing the Ram-Air intake and molded Ballistic filter housing is a basic remove-and-replace operation.

14. The Ford's engine management computer is under the dash on the driver side. Plugging the OttoMind module into the computer is quick and easy.

15. The author and Gale Banks Engineering's performance engineer are suitably impressed with the dyno performance of the test truck, especially the loaded-acceleration dyno test. We set the dyno to simulate the maximum towing capacity of the truck.
