JBA 16-20 Nissan 5.6L VK56VD 1-3/4in Primary Raw 409SS Cat4Ward Header

When you're looking to get more out of your 2014-2022 Infiniti QX80, the JBA Cat4Ward headers are a solid choice. What you get in this package are the headers themselves, constructed from raw 409 stainless steel, along with factory-style emission connections and high-quality hardware designed for a professional installation. These headers are a significant upgrade over the stock exhaust manifolds, offering a less restrictive path for your exhaust gases. This improved flow can lead to noticeable gains in engine power and efficiency, making your QX80 feel more responsive.

The construction here is built to last. The tubing is mandrel-bent from 409 stainless steel, which is known for its durability and resistance to corrosion, making it suitable for daily driving and even tougher conditions like towing. The flanges are a stout 3/8 inch thick with oversized exhaust ports, ensuring a solid seal and efficient gas transfer. A key feature is JBA’s proprietary Firecone collector design, which uses race-proven technology to maximize power and torque gains in the RPM range you'll use most often. The extra-thick collector domes also contribute to the overall robust build of this header system.

Installing these headers is a direct fit for the specified Infiniti QX80 models, as well as compatible Nissan Armada and Titan trucks. The included hardware and factory-style emission connections aim to make the installation process as straightforward as possible, helping to ensure a leak-free seal right from the start. If you're looking to improve your vehicle's performance and want a well-built exhaust component that can handle the demands of everyday use, these JBA headers are a strong contender.
