JBA 04-15 Nissan 4.0L V6 1-5/8in Primary Silver Ctd Cat4Ward Header

If you're looking to get more out of your 2005-2019 Nissan Frontier, Pathfinder, or Xterra with the 4.0L V6 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 easier, which can lead to improved power and better fuel efficiency. These headers are built to handle the demands of daily driving, towing, or even some spirited off-road use.

JBA constructs these headers from durable stainless steel tubing that's bent using a mandrel process to maintain consistent diameter throughout. This ensures smooth exhaust flow. The flanges are a stout 3/8-inch thick and feature oversized ports to match the engine's cylinder heads, further reducing restrictions. A notable feature is JBA's proprietary Firecone collector, which uses race-proven technology to help maximize torque gains in the RPM range you'll use most often. They also include factory-style connections for your emissions equipment and all the necessary hardware for a professional, leak-free installation.

This kit comes with everything you need to get these headers installed, including the high-quality hardware. Make sure to check the manufacturer's installation instructions for any specific details regarding the process for your vehicle.
