JBA 11-14 Ford Mustang GT/GT500 5.0L/5.4L/5.8L 409SS Dual Rear Exit Cat-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.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
