Product Description

The JBA 2011S Shorty Headers are high-performance stainless steel exhaust headers engineered for 2005-2007 Toyota Tundra and 2005-2007 Toyota Sequoia trucks equipped with the 4.7L V8 engine. These Cat4ward® shorty headers replace the restrictive cast iron factory manifolds with mandrel-bent 1.5" primary tubes and JBA's Firecone® merge collectors, improving exhaust scavenging, throttle response, and low-to-mid RPM power gains over stock manifolds.

Constructed from durable 409 stainless steel with thick machined flanges and supplied with all necessary gaskets and hardware, the 2011S headers provide a direct-fit installation that maintains emissions compliance in most states when installed per manufacturer instructions. Ideal for daily drivers, towing applications, and light performance upgrades, these headers deliver a noticeable performance improvement without the complexity of long-tube headers.
