3.7L Shorty Headers

The JBA 1618S is a performance shorty header engineered as a direct replacement for the factory manifold on 2011-2017 Ford Mustangs equipped with the 3.7L V6 engine. Constructed from durable, mandrel-bent stainless steel tubing with a 0.059-inch wall thickness, this header is built to withstand the demands of daily driving, towing, and racing. The header features 3/8-inch thick machined flanges with oversized exhaust ports for optimal flow and includes extra-thick collector domes. It also comes with factory-style emission connections, ensuring compatibility with emissions systems. Mounting hardware and gaskets are included for a professional, no-leak installation, with the header itself being uncoated and grey with a matte sheen. The CARB EO Number is D-57-48, making it 50-state legal when installed according to the manufacturer's guide and instructions.
