Unleashed Sound. The factory exhaust manifolds on your F-150 leave plenty to be desired in the ways of sound, power, and reliability. If you want to upgrade your 1999-2003 Ford with a manifold kit that sounds as mean as it performs, it's time to invest in Dynatech 1-5/8 in. SuperMAXX Long Tube Headers. They unleash the sound of your 5.4L and pick up plenty of power Ford left on the table.

Better Performance. The SuperMAXX kit makes for a dramatic increase in exhaust outflow, which is exactly what your larger V8 needs to breathe and perform. The SuperMAXX kit is an even better solution for supercharged applications. To be sure, these headers are one of the most powerful bolt-on exhaust solution for the 5.4L F-150.

Solid Construction. The SuperMAXX is constructed of quality stainless steel that resists corrosion and rust. Featuring large 1-5/8" diameter primary tubes and 2-1/2" collector housings which are mandrel-bent for smooth flow, these headers minimize back pressure and exhaust restrictions to pump out that nasty sound and power.

Installation and Tune. The Dynatech SuperMAXX doesn't mess around when it comes to increasing exhaust outflow, and because it's so efficient, your F-150 will require a tune for proper performance. Investing in a handheld tuner will help unlock your truck's potential with even bigger gains, and tuning your computer for this header kit takes just a few minutes.

Application. The Dynatech 1-5/8 in. SuperMAXX Long Tube Headers are specifically designed as a bolt-on upgrade in sound and power for any 1999-2003 5.4L F-150.

Please Note. These Long Tube Headers are designed to be used with Dynatech Mid-Pipe's, part numbers 722-84220, 722-84320 or 722-84330.

I noticed that this product comes with new mounting bolts but not new gaskets, does that mean I could re-use my factory gaskets or do you sell gaskets made for this as well as a separate product?


  • The Dynatech 1-5/8 in. SuperMAXX Long Tube Headers actually does come with gaskets, in addition to the header bolts and installation hardware.

Will these fit a crewcab 4x4??


  • These Dynatech 1-5/8 in. SuperMAXX Long Tube Headers will fit any 99-03 5.4L F-150 regardless of cab size or drive.

I know these are for the 5.4. I have seen on forums that they will fit the 4.6 head. I was wondering if they would. They seem to be the same bolt pattern and the ports are the same size and in the same place. So is it a possibility they will work on the 5.4?


  • The Dynatech 1-5/8 in. SuperMAXX Long Tube Headers are designed specifically for 5.4L V8's in the 99-03 F Series. Fitment on any other year, model, or engine cannot be guaranteed. The 4.6L 2v and 5.4L 2v will share a similar bolt pattern, however the difference in engine height can cause alignment issues with the rest of the exhaust and clearance issues on the frame, motor and trans.
