What material is it made of?

The body of the silencer is made of titanium. This allows not only considerably lighten the weight (since titanium is one of the lightest metals of all the components used in exhaust manufacturing), but also quickly dissipate accumulated heat .

The high quality and strength of this material makes it difficult to manufacture, but results in products that are much more durable, stable, and highly heat-resistant.

The collector is made of stainless steel high quality austenitic, which offers high resistance to corrosion, Improved high temperature strength properties and improved formability.

The durability of the materials used in its development is track-tested to ensure optimal performance on the road.
