JBA 04-15 Nissan 5.6L VK56DE Oval Port 1-5/8in Primary Raw 409SS Cat4Ward Header

If you're looking to get more power and better sound out of your 2004-2015 Nissan Titan, swapping out the restrictive factory exhaust manifolds for a set of JBA Cat4Ward shorty headers is a solid move. These headers are designed to significantly increase the power and efficiency of your 5.6L VK56DE engine by allowing exhaust gases to flow much more freely than the stock setup.

JBA builds these headers from durable 409 stainless steel, so they're well-built to handle the demands of daily driving, towing, or even some spirited off-roading. The tubing is mandrel bent for smooth airflow, and the flanges are a beefy 3/8-inch thick with oversized ports to match the engine's oval exhaust ports. A notable feature is JBA's proprietary Firecone collector design, which uses race-proven technology to help maximize power and torque gains right where you need them most – in the typical RPM range for trucks like the Titan. They also include factory-style connections for your emissions equipment and come with high-quality hardware to ensure a professional, leak-free installation.

This kit is designed as a direct fit for your Titan, Armada, or QX56, and includes everything needed for installation, including the necessary hardware and provisions for your emissions hookups. You'll notice an improved throttle response and a deeper exhaust note after installation.
