JBA 65-73 Ford Mustang 351W SBF 1-5/8in Primary Ti Ctd Mid Length Header

If you're working on a 1964-1973 Ford Mustang with a 351 Windsor Small Block Ford (SBF) engine, these JBA mid-length headers are a solid upgrade. They replace the restrictive factory exhaust manifolds with a much freer-flowing design, which can significantly increase your engine's power and efficiency. JBA builds these headers from durable stainless steel, so they're made to handle the demands of daily driving, towing, or even some track time. The tubing is mandrel bent for smooth airflow, and the flanges are a beefy 3/8-inch thick with oversized ports to match the engine's exhaust ports. This means less restriction right from the cylinder head.

A notable feature is JBA's proprietary Firecone collector design. This isn't just for looks; it's a race-proven technology aimed at maximizing torque and horsepower gains in the RPM range you'll use most often. The titanium coating helps manage heat and adds a layer of durability. These headers also include factory-style emission connections, so you can retain your emissions equipment for a cleaner, more compliant exhaust system. They come with high-quality hardware to help ensure a professional, leak-free installation. You'll also find extra-thick collector domes, which contribute to the overall robust construction.

When installing these headers, be aware that they are not CARB approved and cannot be shipped to California. It's always a good idea to refer to the manufacturer's installation instructions for specific details on hardware usage and connection points to ensure a proper, leak-free seal.
