About JBA Performance Exhaust

JBA is one of the most trusted names in the aftermarket exhaust industry because of our commitment to manufacturing excellence. Our product designs are original, innovative and always deliver. Power, quality, fit, durability, and emissions legality are what we are known for. In 1987, those qualities were not present in the header or exhaust industry, so JBA set out to build our own products to meet the needs of the growing street performance market. Originally developed for the 5.0L Mustang, JBA's replacement Cat4Ward headers were engineered with heavy-duty features, easy installation, a durable design, and emissions legal status that made them an instant hit with automotive enthusiasts across America. As demand grew and emissions regulation increased, we saw the need to broaden our product line to cover most popular GM, Ford, Dodge, Jeep, Nissan and Toyota vehicles. We have applied our manufacturing philosophy and build qualities to our entire product line to offer you the most complete line of quality 50 sate emissions legal exhaust products in the industry. Today we offer a variety of products to meet the demands of the performance enthusiast; JBA Cat4Ward Headers, JBA Performance Exhaust Systems, JBA PowerCables ignition wires and our new line of Long Tube Race Headers, all available direct from this website or through our network of installers, retailers, and mail order performance retailers.
