JBA 05-10 Ford F-250/F-350 5.4L 3V 1-5/8in Primary Raw 409SS Cat4Ward Header

If you're looking to get more out of your 2005-2010 Ford F-250 or F-350 with the 5.4L 3V engine, these JBA Cat4Ward headers are a solid upgrade. They're designed to be significantly less restrictive than the factory exhaust manifolds, which can help your engine breathe better and make more power. This means you might notice improved throttle response and a bit more grunt, especially when you need it for towing or daily driving.

JBA builds these headers from durable 409 stainless steel, so they're well-made to handle the rigors of truck life, whether you're on the road or working hard. The primary tubes are 1-5/8 inches, and they feature JBA's proprietary Firecone collector design. This collector is said to help maximize power and torque gains in the RPM range you'll use most often. The flanges are a stout 3/8 inch thick with oversized ports, and the tubes are mandrel bent to maintain consistent diameter throughout. They also include factory-style emission connections, and JBA provides high-quality hardware to help ensure a professional, leak-free installation.

When installing these, you'll want to make sure you have the right tools and refer to the manufacturer's instructions for the best results. Because these are a performance exhaust component, you might also want to consider how they'll pair with the rest of your exhaust system to achieve the sound and performance you're after.
