MIVV: Performance e Sound
Our company’s goal is to create exhausts with high technological standards. To achieve this, our products must be constantly tested to extract their maximum performance.
The engineers working in our Research and Development department have access to a state-of-the-art facility and equipment, including a semi-anechoic chamber for noise measurements in controlled conditions, as well as various types of engine test benches (a static eddy-current bench, a roller bench, and two dynamic benches).
The types of measurements we perform are: exhaust system performance, acoustic measurements, and temperature measurements.
Once the motorcycle is selected for prototype development, it is refined based on the results obtained from the test bench and a series of sound measurements that allow the total noise to be calibrated within legally permitted levels without compromising the exhaust system’s performance. Finally, temperature measurements under stress are used to identify potential critical issues that could arise in particularly stressed components.
Design
It is our duty to meet the needs of those who love to stand out, even through the appearance of their motorcycle.
The design of our exhausts is therefore a fundamental component of our work, which is why it is developed in collaboration with specialized designers in the motorcycle industry.
Over the years, many of our innovative design projects have been patented.
Materials
To manufacture our exhausts, we choose the best materials available on the market.
The most technically advanced versions, usually used in professional settings (Full System Titanium), are developed using Grade 1 slow titanium, a metal that, compared to standard steel, allows a 40% weight reduction. However, at high temperatures, titanium absorbs oxygen, becoming brittle and therefore less suitable for the heat levels imposed by engines. For these applications, we use special titanium alloys that limit oxygen absorption and can better withstand temperatures exceeding 800 °C, all without sacrificing the lightness of titanium.
The choice of thickness is also crucial, as it affects both the weight and the fatigue resistance of the product. To achieve these characteristics, we have implemented production technologies that allow us to work with very thin materials (from 0.6 mm to 1 mm). The carbon used in our exhausts is 3K twill 200 g/m², impregnated with special resins capable of withstanding high temperatures. In the purely racing versions, we can ensure resistance above 200 °C.
Finally, we pay great attention to sound-absorbing materials, which are essential for reducing noise and heat, using cartridges made from a combination of fabrics (14-micron CE textured) specifically designed to dampen noise, especially at high frequencies, and capable of withstanding high temperatures.
