JBA 04-15 Nissan 5.6L VK56DE Oval Port 1-5/8in Primary Ti Ctd Cat4Ward Header

If you're looking to get more out of your 2004-2015 Nissan TITAN's 5.6L VK56DE engine, these JBA Cat4Ward shorty headers are a solid option. They replace the restrictive factory exhaust manifolds with a design that allows your engine to breathe much more freely, which can lead to improved power and better efficiency. These are built for the long haul, constructed from durable stainless steel that can handle daily driving, towing, or even some spirited use.

What sets these headers apart is JBA's proprietary Firecone collector design. This isn't just about looks; it's a race-proven technology aimed at maximizing power and torque gains right where you'll notice them most in your truck's typical RPM range. The tubing is mandrel bent for smooth airflow, and the flanges are a stout 3/8-inch thick with oversized ports to match the exhaust flow. Plus, they include factory-style emission connections and all the necessary hardware for a professional installation that shouldn't leak.

This set is designed as a direct replacement for your stock manifolds, fitting a range of vehicles including the Nissan TITAN, Armada, and Pathfinder, as well as the Infiniti QX56. You'll want to refer to the manufacturer's installation instructions for specific details on connecting the emission components and ensuring a leak-free seal.
