# JBA 65-70 Ford Mustang 260-428 409SS Dual Turn Down Under Rear Valance Header Back Exhaust

When it comes to performance exhaust systems, most people are looking for three things: Power. Sound. Quality. JBA Exhaust Systems deliver the best of all three. While there is high demand for performance and sound, the capacity for power in a JBA Exhaust System gives us the edge. Each system is tuned to provide the best possible exhaust tone without being overwhelming inside your vehicle. By replacing the restrictive factory exhaust system with free-flowing mandrel-bent stainless steel tubing and quality performance mufflers, JBA has developed the power, sound and efficiency you desire for your car, truck or SUV.
