JBA 07-09 Toyota 4.7L V8 1-1/2in Primary Raw 409SS Cat4Ward Header

When you're looking to get more out of your 2007-2009 Toyota Sequoia with the 4.7L V8 engine, this JBA Cat4Ward header set is what you get in the box: the headers themselves, made from 409 stainless steel tubing, featuring 3/8" thick machined flanges with oversized exhaust ports, extra thick collector domes, and JBA's proprietary Firecone collector design. You also get factory-style emission connections and high-quality hardware to ensure a professional, no-leak installation. These headers are designed to be significantly less restrictive than your factory exhaust manifolds, which can help increase your engine's power and efficiency.

The construction here is solid. The 409 stainless steel tubing is chosen for its durability, able to handle the demands of daily driving, towing, or even spirited driving. The 3/8" thick flanges are machined for a flat, secure mating surface to the cylinder head, and the oversized ports are matched to the header tubing to keep exhaust gases flowing smoothly. JBA's Firecone collector is a key part of their design, aiming to maximize power and torque gains in the RPM range where you'll likely be driving most often. Mandrel-bent tubing also ensures consistent diameter throughout the pipe, preventing restrictions that can occur with crush-bent tubing.

Installing these headers is a common way to wake up the performance of your Sequoia or Tundra. Because they are designed to connect to your factory emission controls, you can maintain compliance while still seeing improved performance. The included hardware is there to help make the installation process as straightforward as possible, aiming for a secure and leak-free fit right from the start. If you're looking to improve your truck's breathing and unlock some extra power, this header set is a well-built option.
