When Ford announced the new Coyote engine would be inserted under the hood of F-150s, the forums were buzzing with speculation. Now that it has been out for a few years it's time for us to see how the aftermarket has responded with tried-and-true bolt-ons. Hunting for power, we tracked down new long-tube headers and stainless exhaust kit from American Racing Headers. The headers (PN F150L34W/C, $1,665) feature 1¾-inch diameter primary tubes, a 3-inch Y-pipe with high-flow catalytic converters, and new bolts to replace the factory manifold studs. The after-cat exhaust (PN F150CTBK11, $1,295) is a 3-inch design with resonator and high-flow muffler. It also has all of the necessary clamps and hardware. To do the install, we set aside a lift in our Irvine tech center, and a solid eight hours.
The installation of the headers was fairly straightforward on paper, but given the fact that the Coyote motor is a lot wider than previous truck V-8s, it was more difficult than anticipated. All said and done, the new exhaust added nine rear-wheel-horsepower and six lb-ft of torque. This isn't a monster number, but as with all long-tubes, the ECU needs to be tuned to handle the better breathing and at press time we didn't have a chance to put a custom tune in the computer. Once we've got the truck tuned and back on the dyno, you'll be able to see the new results, as well as be able to hear the exhaust system in action at truckin.com. If your new F-150 is equipped with the 5.0L V-8, give American Racing Headers a call to give it an aggressive truck growl and reap the reward of more power while you're at it.
