JBA 10-19 Toyota 4.6L V8 1-5/8in Primary Raw 409SS Cat4Ward Header

Starting with 3/8-inch thick machined flanges and oversized exhaust ports, these JBA Cat4Ward headers are built to handle the demands of your 2010-2019 Toyota Tundra. The primary tubing measures 1-5/8 inches, designed to help your 4.6L V8 engine breathe more freely than it can with the stock exhaust manifolds. This improved airflow is key to unlocking more power and better efficiency, especially in the RPM range where you do most of your driving.

Constructed from durable 409 stainless steel, these headers are well-built to resist corrosion and endure the rigors of daily driving, towing, or even occasional track use. JBA's proprietary Firecone collector design is a notable feature, utilizing race-proven technology to maximize torque and power gains. The tubing is mandrel-bent to maintain consistent diameter throughout, ensuring smooth exhaust flow. Extra thick collector domes add to the overall robustness of the header assembly.

Installation is made more straightforward with factory-style emission connections included, and high-quality hardware is provided to help ensure a professional, no-leak seal. These headers are a significant upgrade over restrictive stock manifolds, offering a substantial increase in performance for your Tundra.
