2015–2023 Mustang GT 5.0L Long Tube Headers – Performance Connect / Unholy Union | Stainless Works

Take your Coyote-powered Mustang to the next level with the Stainless Works 2015–2023 Mustang GT 5.0L Long Tube Headers – Performance Connect, Unholy Union. Engineered for maximum flow and power, these headers are designed to unleash the full potential of your Mustang GT, delivering improved horsepower, torque, and an aggressive exhaust tone.

Constructed from 304 stainless steel for superior strength and corrosion resistance, these headers are built to perform on the street or track. Precision CNC mandrel-bent tubing ensures smooth, unrestricted airflow. Starting with CNC-cut 3/8" thick flanges, the design flows into 2" diameter primaries and transitions into 3" slip-fit collectors with an integrated merge spike to optimize exhaust scavenging. From there, the system connects to 3" high-flow catalytic converters for enhanced performance.

With extended leads, this system is designed to integrate seamlessly with Stainless Works, MBRP, and Corsa catback systems, giving you the ultimate flexibility in aftermarket exhaust setups—what we call the Unholy Union.

Each header is fully TIG-welded and back-purged for strength, durability, and a precision fit. Finished in a race-inspired mill finish, these headers are proudly made in the USA and backed by a lifetime warranty.

What happens if I don't like it?

How fast is shipping?

Shipping will depend on availability of parts. While we stock our most commonly sold parts we do not stock all parts. If a part is on back order or has a lead time we will communicate with you through the whole process so your are not left wondering why a part hasn't shipped yet.
