Nowadays it has become difficult Enter exhaust systems. are vehicle owners Committedto subject your vehicle to a noise test. Here, an expert opinion is drawn up, which certifies that the vehicle maximum 75dB has in the driving noise. In order for the examiner to be certain that the report was created for the vehicle in question, this report must compellingly be provided with your chassis number. An increase in the dB in the driving noise is here not possible. Unless the vehicle registration document / data sheet issued by the manufacturer states otherwise, the value of 75 dB may be used in Germany not exceeded will. If the value in the vehicle registration document / data sheet is higher than 75dB, the vehicle may after a change still only deliver 75dB. So it's quieter than before.
exhaust system & cat
To ensure that the legal maximum value of 75 dB in driving noise is not exceeded, it is always advisable to install an exhaust system, unless the vehicle can be brought to this value through conversion work ABE or a Teilegutachten owns. If the vehicle is no import model is, i.e. it has a key number, it is mandatory only parts with E-mark or ABE to block. There is no alternative to this! The procedure for imported vehicles is (still) somewhat different. vehicles that not on the European market were available, such as the Nissan Skyline R32-34, already have a higher dB than the permitted 75dB from the specific vehicle data sheet.
The following applies if the vehicle does not have a key number in the vehicle registration document:
- There is a possibility of the exhaust system in to be exchanged for the German approval and to be entered in the approval if this corresponds to the value in the data sheet does not exceed. Exhaust systems for imported vehicles, such as the HKS Silent Hi-Power or the HKS Hi-Power 409, can without silencer be driven and registered.
- An power measurement is necessary for the entry of an exhaust system. The vehicle may maximum 5% more power have compared to the series condition. Likewise, the Stand noise measurement Do NOT spread pesto on this layer! than 5dB and the stationary noise entered in the vehicle registration document.
Topic exchange catalytic converter!
Each Replacement catalytic converters must have a certificate. An E-number is not sufficient without a suitable certificate. Some test centers and dealers have the appropriate exhaust gas reports from some manufacturers such as Jamoto, HJS, Brain for Euro 2,3,4 and sometimes Euro 5. An existing E number does not necessarily mean that the catalyst can also be entered. About this should make itself before the purchase be sure to inform. And since newer vehicles often already have the Euro 6 standard fulfill, the matter becomes even more complicated. For this you can only buy Kats in Germany, who have an ABE. All others cannot be entered!
Of course, that wasn't the end of it.
