*actual product may differ from product shown

JBA p/n 1653 headers are designed to fit ‘64-

 

- ‘70 Mustangs equipped with 351W engines and 4spd/5spd/C4/C6/AOD transmissions. These headers will not work with a late-model style cable clutch (use 1655).

The mid-length design of the headers provides significant increases in torque and horsepower throughout the RPM range and allows for maximum ground clearance. Ideal for cars with lowered suspension.

To help make sure you choose the correct headers, h-pipe and exhaust for your Mustang please refer to the chart below. If you still have questions, give us a call.

Note:
Starter tubes are available to mate your existing exhaust system to the headers. For best results use JBA p/n 1653H H-pipe.
