HJS ECE Tuning Downpipes

We offer a wide range of tuning downpipes tested according to UN ECE Regulation No. 103. This regulation describes uniform conditions for the approval of motor vehicle replacement catalytic converters and is valid in all countries that have joined the United Nations Economic Commission for Europe. Germany is a member state of this agreement (E1).

Our ECE Tuning Downpipe may be used as a replacement part for the standard catalytic converter, provided that the vehicle type in question is listed in the area of use of the catalytic converter approval. A change acceptance or correction of the vehicle documents is not necessary. However, it is a prerequisite that the vehicle drivetrain (engine, transmission, engine control unit, etc.) is in the standard condition.

The respective area of application can be found in the supplied installation instructions or under Downloads.
