JBA 11-14 Ford Mustang 5.0L Coyote 1-3/4in Primary Raw 409SS Cat4Ward Header

If you're looking to get more out of your 2011-2014 Ford Mustang with the 5.0L Coyote engine, these JBA Cat4Ward headers are a solid choice. They replace the restrictive stock exhaust manifolds with a less restrictive design, which helps your engine breathe better. This improved flow can lead to noticeable gains in horsepower and torque, especially in the RPM range you use most often for daily driving and spirited runs.

These headers are built from 409 stainless steel, a well-built material that stands up to the heat and stress of the exhaust system. The primary tubes measure 1-3/4 inches, which is a good size for the Coyote engine to improve flow without sacrificing too much low-end torque. JBA uses a proprietary Firecone collector design, which is their take on a race-proven technology aimed at maximizing power output. The flanges are a stout 3/8 inch thick with oversized ports, and the tubing is mandrel bent to maintain consistent diameter throughout for smooth airflow. They also include factory-style emission connections, making it easier to hook up your stock catalytic converters for a cleaner exhaust system and a professional, no-leak installation.

When installing these headers, you'll want to have the necessary hardware ready. JBA includes high-quality hardware to help ensure a secure fit. Because these are a performance exhaust component, you might also consider pairing them with a high-flow exhaust system or a custom tune to really unlock their full potential. Remember to check your local emissions regulations, as modifications to exhaust systems can affect compliance.
