Description

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.
