2004-2008 F150 5.4L Dynatech SuperMAXX 1-5/8" Long Tube Headers

Get Huge Power Gains and a Brutal, New Exhaust Note

The factory exhaust manifolds of your truck's 5.4L Triton V8 are one of its weakest links when it comes to both reliability and making power. If you want something that will bring your 2004 to 2008 F150 5.4L up to the next level, then you'll need to grab this pair of awesome long tube headers from Dynatech. As part of their SuperMAXX series, these long tube headers were carefully designed to give your truck a dramatic improvement in exhaust outflow which leads directly to devastating horsepower and torque gains for your F150. Each of these headers bolt on right in place of your stock manifolds and have large, highly-efficient primary tubes that shuttle exhaust gasses out of your truck's cylinders much more efficiently than stock, allowing your big Triton V8 to breathe much easier and make huge power gains, especially in supercharged applications. These headers are one of the most powerful bolt-on parts available for your truck and will also provide an intense, screaming exhaust note while they're at it.

Large-Diameter Tubing with Smooth Bends

Each of the headers included in this kit feature large, 1-5/8" diameter primary tubes that are all mandrel-bent for smooth exhaust outflow and to minimize back pressure and restrictions. These headers come standard with 2-1/2" collector housings that allow for excellent exhaust scavenging and hook directly up to Dynatech's lineup of SuperMAXX mid-pipe systems. The headers are made entirely out of high-quality stainless steel to help resist against corrosion. The headers come with new gaskets, hardware, and detailed instructions to help you get these headers and their accompanying mid-pipe installed and running on your truck.

These headers are for off-road use only and may not be street legal in your area.
