JBA 05-07 Toyota 4.7L V8 1-1/2in Primary Raw 409SS Cat4Ward Header

When you're looking to get more out of your 2005-2007 Toyota Sequoia or 2005-2006 Tundra, this JBA Cat4Ward header set is what you get: the headers themselves, made from 409 stainless steel, featuring 1-1/2 inch primary tubes and a raw finish. You'll also find factory-style emission connections and high-quality hardware included, all aimed at making installation as straightforward as possible and ensuring a professional, leak-free result.

These headers are a significant step up from the stock exhaust manifolds. They're built from durable 409 stainless steel, which holds up well to the demands of daily driving, towing, and even spirited use. The tubing is mandrel-bent to maintain consistent diameter throughout, and the flanges are a solid 3/8 inch thick with oversized exhaust ports to help the engine breathe easier. A key feature is JBA’s proprietary Firecone collector design, which uses proven race technology to maximize power and torque gains in the RPM range you'll use most often. This updated design helps improve both power and efficiency by reducing exhaust backpressure.

Installing these headers can make a noticeable difference in how your truck performs. You can expect improved throttle response and a deeper exhaust note. Because they are designed as a direct fit replacement for the factory manifolds, they integrate with your existing exhaust system, including the factory emission connections, simplifying the installation process. Just be sure to refer to the manufacturer's installation instructions for specific details on mounting and hardware usage.
