JBA 00-04 Toyota 4.7L V8 1-1/2in Primary Silver Ctd Cat4Ward Header

When you're looking to get more out of your 2000-2004 Toyota Tundra's 4.7L V8, especially for towing or just daily driving, upgrading the exhaust manifolds is a smart move. These JBA Cat4Ward® shorty headers are designed to replace your restrictive factory exhaust manifolds, helping your engine breathe easier and make more power.

These headers are built from strong stainless steel tubing that's bent using a mandrel process, ensuring consistent diameter throughout for better exhaust flow. The flanges are a solid 3/8-inch thick with oversized ports to match the engine's exhaust ports, and they feature JBA's proprietary Firecone collector design. This design is proven to help generate more power and torque right where you need it most, in the typical driving RPM range. They also include factory-style emission connections and all the necessary hardware for a professional installation that won't leak.

This kit is designed as a direct replacement for your stock manifolds, making installation more straightforward. You'll get improved engine performance and a more robust exhaust system that's built to last through daily use, towing, or even spirited driving.
