Before the systems come onto the market, a prototype is created by the product development department. This is always adapted directly to the vehicle, sound tests are 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. Absorption silencers are used for turbo-powered vehicles and a chamber system for naturally aspirated engines, both are very noise insulating and still have a throaty, sporty sound (of course, this is a matter of opinion). The sports exhaust systems usually all have EC type approval (see description).
