Give your GTD a properly matched Kooks exhaust upgrade
These 2" Kooks headers bring 304 stainless steel construction and V-band collector connections to the 5.2-litre Mustang GTD. Choose the version with or without EGR fittings to match your installation, and pair it with the required Kooks ULTRA X connection and mid-section assembly.
SKUs: 11572600, 11572610
Choose the EGR provision your car needs
11572600 is supplied without EGR fittings. 11572610 includes them. Both use 2" primary tubing and 3" V-band collector connections. That distinction is part of the header specification, so choose it around the actual engine installation.
Complete the upgrade with the matching pipes
Add the GTD ULTRA X mid-section in the Competition Only configuration, or the GREEN-catted version. Each includes the front connections, ULTRA X-pipe and clamps, and joins the OEM axle-back. The gaskets, O2 extensions and header installation hardware come with the headers.

Frequently asked questions
What changes between the two SKUs?
11572610 adds EGR fittings. 11572600 is the version without those fittings.
Can I keep the factory axle-back?
The matching GTD ULTRA X connections and mid-section join the OEM axle-back. The headers require that matching Kooks front arrangement.
Do you recommend tuning with these headers?
We recommend tuning with every header installation. Talk to us about calibration for your vehicle, exhaust and other modifications.
