The catalyst developed by the HJS tuning experts has undergone all stages of development. Manufactured from stainless steel and encased in the calotte thermal insulation used in 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 significantly improved engine response. Naturally, an improvement in performance and torque is clearly noticeable. And last but not least, the metal carrier used ensures a more sonorous sound. With ECE approval, registration in the vehicle documents is not necessary.
