Product Description

The **BBK 18563** is a high-performance long-tube header system designed specifically for the 5.0L Coyote engine in 2015-2023 Mustang GTs. With large 1-7/8" mandrel-bent tubes and a titanium-ceramic coating, this kit offers excellent exhaust flow, heat management, and durability.

Included in the kit is a high-flow catalytic X-pipe, which helps retain emissions compliance while improving performance. The ball-and-socket collector design makes for easier installation and better alignment, while the thick flanges ensure a robust, leak-free connection. This is a bolt-on solution that works with the factory cat-back, making it ideal for those who want serious gains in power and sound without major fabrication work.
