JBA 65-70 Ford Mustang 260-302 SBF 1-1/2in-1-3/4in Primary Raw 409 Tri Y Header

JBA is well-known for exhaust components that help you get the most out of your engine. These Tri-Y headers are specifically made for the 1964-1970 Ford Mustang with a 260 or 302 Small Block Ford (SBF) engine, whether it's a stick shift or automatic. They are designed to increase horsepower and torque across the entire RPM range, making your classic Mustang feel much more responsive.

These headers feature large diameter, mandrel-bent primary tubes that help exhaust gases flow smoothly. The patented JBA Firecone collector is designed to merge these tubes efficiently, reducing back pressure and improving scavenging. The flanges are a solid 3/8 inch thick and are CNC laser-cut for a precise fit, ensuring a good seal with your engine block. They also include oversized exhaust ports and O2 sensor provisions, making them ready for tuning. The raw 409 stainless steel construction is durable and built to last, even in harsh conditions, and they are designed to offer good ground clearance, which is important for lowered vehicles.

This header system comes with all the necessary hardware and detailed instructions to help you get a professional, leak-free installation. Please note that these headers are for closed-course competition use only and are not CARB approved, meaning they cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details.
