Gain Horsepower and Torque. Your exhaust system has a big job to do and it impacts your rig’s overall performance. When you upgrade to these AFE Twisted Steel Long Tube Catted Headers & Connection Pipes, your speed machine achieves tremendous gains. Dyno-testing showed gains of +13 horsepower and +19lbs x ft of torque.

Rumble More Aggressively. Of course, when you upgrade to this header and pipe system, a lot more exhaust flows through. The long tube headers are an optimal length and mandrel bent tubing is a wide 3 inches in diameter. With all that space for powerful flow, the natural result is a deep, aggressive noise.

Improved Catalytic Converter. The connection pipes of this Exhaust Kit incorporate catalytic converters. They integrate powerful 400 cell catalytic converters to ensure you get the best performance.

Constructed for Durability. These Headers and Pipes are reliable. They are made out of 304 stainless steel and are MIG hand welded for precision and strength. Their design includes heavy duty laser cut flanges plus high end gaskets to make a leak free system too. You can seamlessly connect to an AFE cat back exhaust system too because this Kit includes adaptors.

Not CARB Certified. You cannot legally sell or use this Kit on a registered vehicle in California because the Pipes and Headers are not CARB certified.

Installation. For being such an intense upgrade, these Headers and Pipes are refreshingly easy to install. Secure in place through existing factory holes. All the hardware you need is included.

Application. These AFE Twisted Steel Long Tube Catted Headers & Connection Pipes are designed to enhance the 2015 to 2017 Mustang GT.

    Great quality !

    When I first looked at these headers I was a little skeptical as to what performance and quality this product may bring , after I received the product and I installed the numbers on the dyno showed to be as good as any other name brand header out there
