Power Boost for the Track. You may not be able to outfit your street truck with this set of Y-pipes and Twisted Steel headers due to the lack of catalytic converters, but your racetrack vehicle will sing with it on. Add up to 17 HP with this exhaust pipe alone. The Y-pipe design features advanced tricks like merge collectors with mitered edges and extra-gentle bends formed with a mandrel to prevent tool marks or wrinkles. All of it adds up to provide the maximum exhaust flow speed as you're tearing up the track.

Optimization from the Experts. By investing in an exhaust upgrade from AFE, you're buying the engineering expertise of years of testing and adjustments. For example, the length of each part of the Y-pipe was only settled on after exhaustive pulse control tests to determine the optimal system for boosting performance. Maximizing velocity results in faster throttle response.

Installation is a Breeze. Don't worry about struggling to fit the joints together with the rest of your system. Ball sockets and laser-cut header flanges attach equally well to factory connections or other aftermarket parts. Bolt on fasteners fit right into the pre-drilled factory holes.

Application. This aFe Twisted Steel headers and Y-pipe set will fit all of the 2004 to 2008 Ford F-150s that feature a 5.4L engine.
