Description

HJS offers an extensive range of approved tuning downpipes.
The vehicle-specific stainless steel catalytic converters can be combined with standard exhaust systems from many different manufacturers.
De 200 HJS cpsi tuning catalytic converters optimize the car's performance while significantly improving sound.

HJS offers a comprehensive range of tuning downpipes that have been tested according to UN ECE Regulation No. 103. This regulation sets out uniform conditions for the approval of replacement catalytic converters for motor vehicles and is valid in all countries affiliated to the United Nations Economic Commission for Europe. Germany is a Member State of this Agreement (E1).

The downpipe with or without cat is mounted directly on the turbo and is therefore the first part of your exhaust. In modern cars, this part of your exhaust ensures air extraction from the cylinders. With a downpipe, even more air can pass through this, giving you a louder and deeper sound.

The ECE tuning downpipe may be used as a replacement part for the standard catalytic converter, provided the relevant vehicle type is stated in the scope of the catalytic converter approval. A change acceptance or correction of the vehicle documents is not necessary. However, the condition is that the vehicle's powertrain (engine, transmission, engine control unit, etc.) is in standard condition.
