JBA shorty headers are one of the foremost performance upgrades you can bestow upon your beloved car, truck, or SUV. JBA Headers are significantly less restrictive than stock manifolds and dramatically increase the power and efficiency of your engine. Each header is constructed from durable stainless steel to endure the abuse of racing, towing, and daily driving – built to withstand it all. JBA’s proprietary Firecone collector design uses race proven technology for producing maximum power and torque gains where you drive most. Each system includes factory style emission connections and high-quality hardware for a professional no-leak installation.

03-06 GM Truck/Hummer 6.0L
Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components, pedals, shifters, instrument clusters, and adjacent parts can vary between LHD and RHD configurations, but in many cases they are identical depending on the design of the vehicle and part. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.
Increase your horsepower and torque with JBA Cat4ward headers! They are designed with 3/8 in. thick laser-cut flanges, mandrel-bent primary tubes, and feature JBA's patented Firecone merge collectors. They're available in either steel or 409 stainless steel and are offered in a chrome plated or high-temperature silver ceramic finish for most applications. JBA includes premium-quality mounting hardware and instructions for the installation and, unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This would include components such as cylinder heads, chassis, steering, motor mounts, body mounts, bushings, etc. If aftermarket components, parts from other applications, or custom-altered parts are used on your vehicle, it is the installer's responsibility to verify fitment.
