BORLA Performance Industries started over 40 years ago, producing exhaust systems for ultra luxury and ultra performance vehicles including Rolls-Royce and Ferrari. From that history, BORLA developed and patented a host of manufacturing techniques that give their stainless steel exhausts the durability and performance that Jeep drivers flock to. BORLA even patented the way the steel is processed for their Cat-Back system, Header and Axle-Back systems. All use premium, high-quality austenitic T-304 stainless steel, which is better than 409 or aluminized steel. The construction of the exhaust systems is entirely welded and produced with mandrel-bent tubing. It's these high-end manufacturing techniques that make BORLA the go-to exhaust for off-road racers all over the world. Shop Borla Now
