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.
