JBA 67-70 Ford Mustang 390-428 FE 1-3/4in-2-1/2in Primary Ti Ctd Tri Y Header

If you're looking to get the most out of your 1967-1970 Ford Mustang's 390 or 428 FE engine, especially if you've already done some work to it, a set of JBA Tri-Y long tube headers is a solid choice. These aren't just about making noise; they're engineered to significantly improve how your engine breathes, which translates directly into more horsepower and torque, particularly at higher RPMs where you want that extra push.

What sets these headers apart is their construction. You're getting large diameter, mandrel-bent primary tubes made from 304 Series Stainless Steel, which means they're built to last and resist corrosion even in tough conditions. The oversized exhaust ports and the patented JBA Firecone® merged collectors are designed to smooth out exhaust flow, reducing backpressure and helping your engine run more efficiently. The 3/8-inch thick flanges are CNC laser-cut for a precise fit, and the Firecone collector itself has an extended, concave design for even better flow. Plus, JBA pays attention to practical details like ground clearance, so you don't have to worry about scraping the collectors, even on lowered cars.

This system includes all the necessary hardware and detailed instructions to help ensure a professional, no-leak installation. Keep in mind these headers are intended for closed-course competition use only and are not CARB approved, so they cannot be shipped to California. They also carry a Prop 65 warning.
