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, a sound test is carried out, engine efficiency and back pressure are measured. This guarantees 100% fitting accuracy and engine harmony. This is 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)
