      Maximum Performance. Experience an overall increase in power by upgrading to these X-Force 1.875 x 3-Inch Long Tube Headers with High Flow Metallic Catalytic Converters. These high-quality headers let Mustang GT’s engine breathe better by allowing the engine to push the exhaust gases out of the cylinders with more ease. This system also comes with integrated collectors and catalytic converters to facilitate a smoother exhaust flow and reduce turbulence for outstanding exhaust performance.

      Confidently Fierce Exhaust Sound. These X-Force Long Tube Headers enhance your muscle car’s aggressive stance as it gives off a powerfully loud exhaust note. Moreover, this system upgrade appropriately goes with the GT’s engine power performance, giving the vehicle a commanding sound as it accelerates through various driving conditions.

      High-Flow Catalytic Converters. The catalytic converters that come with these 1.875 x 3-Inch Long Tube Headers are designed to deliver enhanced performance compared to the restrictive stock counterpart. Each header features a high-flow catalytic converter with a density of 100 cells per square inch and a metallic substrate. This intensifies the exhaust flow velocity and facilitates continuous breathing of the Mustang’s engine.

      Long-lasting Durability. Built to withstand harsh impacts from the power-generating combustion process, these headers are constructed using a heavy-duty stainless steel tubing. The scavenger-spiked collectors are included to create a smoother path for efficient airflow. Additionally, the header flanges are CNC-machine cut to guarantee a leak-proof operation and are fully welded for a race-proven strength.

      No Tune Required. These 1.875 x 3-Inch Long Tube Headers with High Flow Metallic Catalytic Converters are designed to improve the performance of your car without the need to reprogram the ECU. By utilizing state of the art computer-aided designs, these Headers will increase power using the factory tune.
