      Raised Performance for All Your Adventures. Replacing your rather restrictive exhaust manifold with a high-performance shorty header is a sure-fire way to raise your Mustang GT’s performance. When choosing the right headers for your ride, these Flowtech 1-5/8-Inch Shorty Headers; Black Painted Finish are the way to go. These headers feature plumbing engineered to improve exhaust gas velocity, thus optimizing your engine’s combustion cycles. In doing so, these headers will raise your ride’s horsepower and torque levels, giving it impressive performance for all your driving adventures.

      Bold Race Car Sound. These shorty headers will also improve your ride’s exhaust sound. More to the point, these headers’ free-flowing plumbing will give your ride a bold race car roar that’s sure to make your fellow motorists take notice. What’s more, these headers are designed for maximum clearance, making them ideal for lowered Mustangs.

      Retains Factory Catalytic Converters. These shorty headers will replace your stock exhaust manifolds in between your engine and the factory catalytic converters. This enables these components to continue doing their job in keeping your ride’s emissions levels down.

      Wear-Resistant Build Quality. These shorty headers feature premium 1-5/8-inch wide tubular steel construction that’s CNC mandrel-bent to exact specifications. This construction ensures these headers deliver turbulence-free exhaust gas flow. Furthermore, these headers come with header flanges that are laser-cut from 3/8-inch thick steel for outstanding sealing and maximum strength. Finally, these assemblies are painted in a specialized black coating designed to provide optimum corrosion protection.

      CARB-Certified Under CARB EO Number D-115-19. These Hooker Blackheart shorty headers are CARB-certified under EO number D-115-19, making them legal in all 50 states.

      No Need to Re-Tune ECU. You don’t need to re-tune your ECU for you to benefit from these headers’ performance. Still, it’s always a good idea to re-tune your ECU in the future as this will make sure your Mustang and these components are completely in sync.

      Application. These Flowtech 1-5/8-Inch Shorty Headers; Black Painted Finish fit all 2005 to 2009 Ford Mustang GT models.
