This HJS tuning downpipe is designed for BMW M3 / M4 S55B30A engines. The catalyst developed by the HJS tuning experts has gone through all the development steps. Made of stainless steel and coated with the thermal insulation insulation from motorsport, a high-tech tuning product is now available for BMW drivers. The significantly reduced exhaust back pressure of the HJS tuning catalytic converter not only ensures reduced temperatures in the turbocharger, but also a significantly better engine response. Of course, a performance and torque improvement can be clearly felt. And last but not least, the metal support used ensures a sonorous sound. With the ECE approval, an entry in the vehicle documents is not required.
