This HJS tuning downpipe is designed for BMW M140i / M240i / 340i / 440i / 540i / 740i with Euro 6 B58 B30A engines. The catalyst developed by the HJS Tuning experts has gone through all stages of development. Made of stainless steel and encased with the motor sport dome thermal insulation, a high-tech tuning product for BMW riders is now available. The significantly reduced exhaust backpressure of the HJS tuning catalyst not only ensures reduced turbocharger temperatures, but also significantly better engine response. Of course, a performance and torque improvement is clearly felt. And last but not least, the metal carrier used makes for a sonorous sound. With the ECE approval, registration in the vehicle documents is not required.
