Not permitted for use on public roads.Possibly, after successful noise and performance measurement, the exhaust system can be registered according to §21 StVZO.Description: Our exhaust systems come from Sweden from the brand Simons and are manufactured according to ISO9001:2008 standard. Before the systems are launched on the market, a prototype is created by the product development department. This is always adapted directly to the vehicle, sound testing is carried out, engine efficiency and back pressure are measured. This guarantees 100% accuracy of fit and engine harmony. Because a turbo engine, unlike a naturally aspirated engine, does not require exhaust back pressure. For turbo-powered vehicles, absorption silencers are used and for naturally aspirated engines a chamber system is used, both are very noise-insulating and still have a throaty, sporty sound (of course, this is in the eye of the beholder). The sports exhaust systems usually all have EC type approval (see description).
