JBA Performance Exhaust Cat4ward Headers
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.
