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

If you're looking to give your 1964-1970 Ford Mustang a serious boost in both sound and performance, this JBA header back exhaust system is a solid choice. Designed to replace your restrictive factory setup, it uses free-flowing, mandrel-bent stainless steel tubing and performance mufflers to help your engine breathe easier. This means you can expect a more aggressive exhaust note and a noticeable improvement in how your car performs, especially when paired with aftermarket headers.

This system is built with 409 stainless steel tubing for good durability, and it includes high-flow mufflers that are tuned to deliver a powerful exhaust tone without being overwhelming inside the cabin. The dual turn-down tips are tucked neatly under the rear valance, giving your classic Mustang a clean, performance-oriented look. JBA also includes factory-style hangers and quality hardware to make installation as straightforward as possible, ensuring a proper fit.

When installing this system, it's important to note that it is not CARB approved and cannot be shipped to California. You'll also want to check the manufacturer's instructions for any specific details regarding installation, especially if you're also upgrading your headers at the same time. This exhaust is designed to work with engines from 260ci up to 428ci, offering a significant upgrade for your Mustang's exhaust.
