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 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. For turbo-powered vehicles, absorption silencers are used and a chamber system for naturally aspirated engines; both are very noise-insulating and still have a throaty, sporty sound (depending, of course, on the observer). The sports exhaust systems usually all have EC type approval (see description)
