JBA 40-2653 409SS Dual Through Rear Valance Header-Back Exhaust for 1964-1966 Ford Mustang (260-428)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1964-1966 Ford Mustang models including Base, Shelby GT-350, and Shelby GT-350H (260-428).
The JBA 40-2653 Header-Back Exhaust System is engineered to replace restrictive factory piping with high-flow 409 stainless steel. Designed specifically for the classic Mustang dual through-valance exit, this system balances an aggressive exhaust tone with improved volumetric efficiency. Each kit features large-diameter mandrel-bent tubing to maintain consistent exhaust velocity and reduce backpressure compared to standard crush-bent alternatives.
- Constructed from durable 409 stainless steel for long-term corrosion resistance.
- Mandrel-bent tubing ensures maximum exhaust flow and performance gains.
- Includes high-flow stainless steel mufflers for a deep, tuned sound without excessive drone.
- Finished with polished chrome stainless steel tips for a period-correct aesthetic.
- Uses factory-style hangers and includes high-quality hardware for a precise fit.
- Manufacturer Part Number: 40-2653
