What materials is it made of?

The silencer body is made of aluminum, which allows the exhaust to be much lighter compared to a steel one. This material also dissipates heat more effectively, which contributes to improved performance. Aluminum is highly corrosion-resistant and has a shiny appearance. Furthermore, the exhaust features a black finish, which is achieved through a ceramic-based painting process, resulting in a more aggressive look.

The header is made of high-quality austenitic stainless steel, which offers high resistance to corrosion, improved high-temperature resistance properties, and perfected formability.

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