JBA 65-73 Ford Mustang 351W SBF w/T-5/Cable Clutch 1-5/8in Primary Raw 409SS Mid Length Header

If you're looking to get more power out of your classic 1964-1973 Ford Mustang with a 351W SBF engine and a T-5 or cable clutch, a set of JBA mid-length headers is a solid upgrade. These headers replace the restrictive factory exhaust manifolds, allowing your engine to breathe much more freely. This improved exhaust flow can lead to noticeable gains in horsepower and torque, especially in the RPM range where you do most of your driving.

JBA builds these headers from strong 409 stainless steel tubing, which holds up well to the heat and stress of daily driving and more spirited use. The primary tubes are 1-5/8 inches in diameter, a good size for the 351W to help it exhale efficiently. They feature a 3/8-inch thick machined flange for a solid seal against the cylinder head, and JBA's unique Firecone collector design is proven to help maximize power output. You'll also find that they include factory-style emission connections, making it easier to hook up your emissions equipment for a cleaner running engine and a professional, no-leak installation. Extra thick collector domes add to the overall durability.

When installing these headers, it's important to note that they are not CARB approved and cannot be shipped to California. You'll want to have all the necessary hardware on hand for a smooth installation, as JBA includes high-quality fasteners to ensure a proper seal. This is a significant upgrade for your Mustang's exhaust system, designed to give you that extra bit of performance you're looking for.
