Build Power and Stay Emissions-Legal with JBA Cat4ward Shorty Headers

JBA Cat4ward Headers perform a neat trick. The shorty-style headers improve power—especially midrange torque, right where street engines need it—while being emissions-legal. Designed as direct-fit replacements for factory headers or manifolds, the Cat4wards accept all factory emissions devices and keep the catalytic converter in the stock position, which makes them legal for use in all 50 states.

The Cat4ward headers are packed with power-building features:
• Mandrel-bent 16-gauge stainless steel primary tubes for improved flow and throttle response
• Oversized exhaust ports maintain maximum exhaust velocity
• Firecone® collector design uses race-proven technology for maximum power and torque gains
• 3/8-inch thick, CNC laser-cut flanges and sealing bead to prevent warping and leaks
• Collector domes will not distort and leak like inferior designs

JBA Cat4ward Headers are available with a natural finish. Some applications are available with a silver ceramic coating that can withstand metal temperatures more than 1,500 degrees F or a titanium ceramic coating rated to 1,600 degrees F.

JBA Cat4ward Headers are available for many popular V8-powered passenger cars and light trucks from the 1950s through today. We also have Cat4ward midlength headers for 1965-73 Mustang that are 50-state emissions-legal and universal-fit blockhugger headers for small block Ford that are emissions legal for pre-1967 (49-state) and pre-1965 (CA) vehicles.
