The stock exhaust manifolds on the 11-14 Stangs feature what is arguably the best factory exhaust manifold ever created by Ford; however, there are plenty of performance hindering parts built into them. The Kooks' team took the their time to vastly improve these performance robbing factory manifolds. Gone are the primaries that “Y” or connect to each other. Kooks used individual larger primaries and large collectors to improve flow. Kooks also takes their time to smooth and clean up all welds for optimal flow.

Kooks Custom Headers introduced a great Mustang exhaust solution when they released the Super Street Series shorty headers for the 11-14 Mustang GT & Boss 302. These headers are a direct bolt on install and don't require any custom tuning. Best of all you pick up roughly 10 HP and can still keep your factory mid pipe and catalytic converters.

LatemodelRestoration.com is your source for all of your 5.0L coyote performance needs. Just like these Kooks shorty headers. Wait! Shorty headers? That’s right; they're not long tube headers. And yes your 2011-14 GT or boss 302 does come from the factory with shorty headers.

Difference is these have 1 7/8 inch primaries that allow for that extra flow to give you extra power. Plus these don't require a tune and they will bolt to your factory mid pipe or any aftermarket mid pipe that is intended to be used with the stock headers. Included in the box is a set of steel shim gaskets along with two sets of 10mm bolts. One set of fine thread the other course thread because Ford did change the faster style a couple of times between 2011-2014.
