Product Description

The **BBK 18564** header kit is a high-performance upgrade for 2015-2023 Mustang GTs with the 5.0L engine. Built with CNC-mandrel bent 1-7/8" tubing and a silver-ceramic finish, it's designed to dramatically improve exhaust flow while keeping under-hood temperatures in check.

Thanks to its integrated high-flow catted mid-pipe, this kit offers a refined yet aggressive sound, along with better throttle response and power gains. The ball-and-socket collectors make alignment easy, while the thick flanges provide a reliable seal. Installation is straightforward with its bolt-on design, making this a great choice for street or performance builds.
