Description:
Our exhaust systems come from Sweden from the brand Simons and are manufactured according to ISO9001:2008 standards. Before the systems are released to the market, the product development department creates a prototype. This is always fitted directly to the vehicle, sound tests are conducted, and engine efficiency and backpressure are measured. This guarantees 100% fit accuracy and engine harmony. This is because a turbo engine, unlike a naturally aspirated engine, does not require exhaust backpressure. For turbocharged vehicles, absorption mufflers are used, and for naturally aspirated engines, a chamber system is used; both are very sound-absorbing and still have a robust, sporty sound (of course, this depends on personal preferences). The sport exhaust systems usually all have EC type approval (see description).
