Not permitted for use on public roads.Description: Our exhaust systems come from Sweden from the manufacturer Ray. These are sold under the brand Simons or TA-Technix 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. 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 of which are very noise-insulating and still have a throaty, sporty sound (depending on the observer, of course). The sports exhaust systems usually all have EC type approval (see description).
