Each box must be programmed specifically for the vehicle—so please provide the vehicle identification number!

Product description:
The latest 2.5 TFSI DNWC RS3 generation is equipped with gasoline particulate filters (OPF). If you want the same sound or performance as the non-OPF vehicles, these must be removed. However, if they are simply removed, the vehicle will generate different error codes (engine light etc.) due to the missing filters and the different lambda values. For this reason, we have developed our OPF simulator tool. This allows a downpipe without catalytic converter and without OPF to be installed without an error code or indicator light lighting up. The control unit or software does not need to be adapted for this, which means that retrofitting is possible without leaving any traces. Not only does the sound finally become throaty, powerful and louder again, but the performance also increases by up to20 hp and50 Nm.


Important:
The temperature sensors must still be installed in the downpipe. A DAZA downpipe can therefore not be used 1:1, as the inputs for the temperature sensors are missing. We have corresponding downpipes with all variants of catalytic converters. We guarantee the function of the modules exclusively with our downpipes. We do not accept returns or complaints in combination with other downpipes.
