Product Details

If you're looking to get more out of your 2000-2004 Toyota Tundra with the 4.7L V8 engine, these JBA Cat4Ward headers are a solid choice. They replace the restrictive factory exhaust manifolds with a less restrictive design, which can help your engine breathe better. This improved airflow often translates to noticeable gains in power and overall efficiency, making your truck feel more responsive, especially when towing or carrying a load.

These headers are built from 409 stainless steel, a well-known material for its durability and resistance to corrosion, making them suitable for daily driving and tougher conditions. The primary tubes are 1-1/2 inches in diameter, and they feature JBA's proprietary Firecone collector design. This collector is engineered to help maximize power and torque gains in the RPM range you'll use most often. The flanges are a stout 3/8 inch thick with oversized exhaust ports, and the collector domes are extra thick to handle the heat. They also include factory-style emission connections, so you can retain your emissions equipment for a cleaner exhaust system.

Installation includes high-quality hardware for a professional, no-leak fit. While these headers are designed to fit directly, it's always a good idea to refer to the manufacturer's installation instructions for specific details and any recommended tools or procedures.
