JBA Cat4Ward shorty headers are a premier performance upgrade designed to replace restrictive factory manifolds with a high-flow exhaust solution. Engineered for the rigors of towing, racing, and daily driving, these headers significantly improve engine efficiency and power delivery. The system features JBA’s proprietary Firecone collector, a race-proven design that maximizes torque gains where you need them most in the RPM range.

Constructed from durable 409 stainless steel, the 1-5/8 inch mandrel-bent primary tubes ensure consistent flow and long-term durability. Each set is finished with 3/8 inch thick machined flanges and oversized exhaust ports to prevent warping and ensure a reliable, leak-free seal. These headers include factory-style emission connections and high-quality hardware for a professional installation that maintains your vehicle's original configurations.
