JBA 16-20 Nissan 5.6L VK56VD 1-3/4in Primary Silver Ctd Cat4Ward Header

When you're looking to get more out of your 2014-2022 Infiniti QX80 or Nissan Armada, truck, or Titan, a set of JBA Cat4Ward headers is a solid upgrade. These headers replace your restrictive factory exhaust manifolds, allowing your 5.6L VK56VD engine to breathe much more freely. This means you can expect improved power and better efficiency, especially in the RPM range where you do most of your driving.

What you get in this kit are JBA's well-built shorty headers, constructed from durable stainless steel tubing that’s mandrel bent for smooth airflow. They feature 3/8-inch thick machined flanges with oversized exhaust ports to match the engine's needs, and JBA’s proprietary Firecone collector design is used to maximize power and torque gains. The system also includes factory-style emission connections and high-quality hardware, which are important for ensuring a professional, no-leak installation. The silver coating adds a layer of protection and a clean look.

This is a comprehensive package designed to give your vehicle a noticeable boost in performance. The headers are built to withstand the demands of daily driving, towing, and even some spirited use.
