JBA 65-73 Ford Mustang 260-302 SBF 5 Speed T5/T56 1-3/4in Primary Raw 409SS Long Tube Header

When you're looking to get the most out of your 1964-1973 Ford Mustang's 260 or 302 small block Ford engine, especially when paired with a T5 or T56 5-speed transmission, these JBA long tube headers are a solid choice. They are built to maximize performance gains and improve high-RPM efficiency, giving your classic Mustang a noticeable boost in horsepower and torque across the entire RPM range. This specific set is constructed from 409 Series Stainless Steel, offering a good balance of durability and performance for your build.

What you get in the box are the primary tubes, the patented JBA Firecone® merged collectors, and a set of high-quality hardware, along with thorough instructions to help ensure a professional, no-leak installation. The primary tubes are large, mandrel-bent for smooth airflow, and feature oversized exhaust ports. The flanges are a thick 3/8 inch, CNC laser-cut for a precise fit, and include O2 sensor provisions. JBA designed these headers with maximum ground clearance in mind, which is a real plus, especially if your Mustang is lowered, helping to prevent the collectors from dragging.

Keep in mind that these headers are intended for closed-course competition use only and are not CARB approved, meaning they cannot be shipped to California. If you're aiming for serious performance improvements on your classic Mustang, these JBA long tube headers are a well-built option to consider.
