JBA 65-73 Ford Mustang 351W SBF 1-3/4in Primary Raw 409SS Long Tube Header

Starting with the 3/8-inch thick, one-piece flanges, these JBA long tube headers are built solid for your 1964-1973 Ford Mustang with a 351W SBF engine. The large, 1-3/4 inch diameter primary tubes are mandrel-bent to maintain their shape and ensure smooth airflow, which is crucial for getting the most out of your engine, especially at higher RPMs. JBA's patented Firecone® collector design helps merge the exhaust gases efficiently, reducing turbulence and further boosting horsepower and torque gains across the entire power band.

These headers are constructed from 409 Series stainless steel, offering a good balance of corrosion resistance and durability for everyday driving. The oversized exhaust ports are designed to match the engine's cylinder heads, preventing bottlenecks. You'll also find O2 sensor provisions, making it easier to integrate with your existing or upgraded exhaust system. JBA also pays attention to practical installation details, designing these headers for maximum ground clearance, which is a big help on lowered vehicles to avoid dragging the collectors.

This system comes with all the necessary hardware and detailed instructions to help ensure a professional, no-leak installation. 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 looking to unlock the full performance potential of your Mustang's 351W engine, these long tube headers are a well-built option.
