Description:
Our exhaust systems come from Sweden from the brand Simonsand are manufactured according to the ISO 9001:2008 standard. 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 turbocharged 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 highly sound-absorbing yet still produce a robust, sporty sound (though this is, of course, a matter of personal preference). The sports exhaust systems usually all have EC type approval (see description).
