HJS-Downpipe BMW 540i/640i/740i/840i/M340i xDrive, Z4 M40i, Toyota Supra, 3.0 - EURO 6d-TEMP, 300 Cp

This HJS tuning "downpipe" is designed for BMW 540i/xDrive, 640i/xDrive, 740i xDrive, 840i/xDrive, M340i xDrive, Z4 M40i and for Toyota Supra with Euro 6d-TEMP 3.0l B58 B30C/B engines. The catalyst developed by the HJS tuning experts has gone through all development steps. Made of stainless steel and covered with thermal insulation from motorsport, a high-tech tuning product is now available for BMW and Toyota Supra 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, an improvement in performance and torque can be clearly felt. And last but not least, the metal carrier used ensures a more sonorous sound. With the ECE approval, an entry in the vehicle documents is not required.
