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 tests are carried out and engine efficiency and back pressure are measured. This guarantees 100% accuracy of fit and engine harmony. This is because a turbo engine, unlike a naturally aspirated engine, does not require exhaust back pressure. Turbocharged vehicles use absorption mufflers and naturally aspirated engines use a chamber system, both of which are very quiet and still have a throaty, sporty sound (of course, this is up to the observer). The sports exhaust systems usually all have EC type approval (see description).
