JBA Cat4Ward shorty headers are a premier performance upgrade designed to replace restrictive factory exhaust manifolds. By reducing backpressure, these headers significantly improve engine efficiency and power output. Constructed from 409 stainless steel, they are engineered to withstand the thermal stress of heavy towing, racing, and daily transit. These headers feature JBA’s proprietary Firecone collector technology, which optimizes exhaust scavenging for increased torque across the RPM range. Each set includes 3/8-inch thick machined flanges to prevent warping and factory-style emission connections for a straightforward installation.
