The objective of ProRacing® is to produce exhausts of a highest technical caliber. For this, we need to make sure that our products consistently undergo quality assurance, so that maximum performance can be obtained.
Performance and Sound
Our engineers of our Research and Development team take advantage of our state of the art premises and equipment, which includes a semi-anechoic chamber for the measurement of noise in controlled environmental conditions, as well as many types of engine bench testing.
Our measurement calibrations include: exhaust system performance; temperature measurements, and sound db. measurements.
Once a motorcycle is identified for prototype and has been selected, experimental checks begin on the bench test, and on a range of noise measurements that give us the possibility of calibrating the noise levels within the limits permitted by law. We do this without jeopardizing the performance of the exhaust system. We examine temperature measurements under intense stress, highlighting critical issues that could occur on parts undergoing particularly intense levels of stress on and off the track.
For us, performance isn’t the only criteria we look at. We know your bike is your pride and joy and it is our duty to make it look distinguished carrying our performance products. The look of our exhausts is therefore fundamental in all of our product development. Design specialists are an integral part of the overall process.
Design patents are a big part of the innovative design process.
For our exhausts, we use the best materials available in the world.
The most technically advanced models, normally used in the racing world (Full System Titanium), are developed using grade 1 slow titanium, a metal that offers a 40% weight reduction when compared with base steel. At high temperatures titanium absorbs oxygen, becoming brittle, and therefore is not well suited to the heat levels imposed by racing engines. For these applications, we use special titanium alloys capable of limiting oxygen absorption, and therefore are more capable of withstanding temperatures exceeding 1475°F, whilst maintaining the weight reduction of titanium.
Of fundamental importance is also the selection of the thickness, which impacts on the weight and the resistance to stress of the product. In order to obtain these characteristics, we have implemented production technologies that enable us to process minimal thicknesses (0.6 to 1 mm). The carbon used for our exhausts is twill 3k 210 g/sqm, impregnated with special resins that can withstand high temperatures. With competition versions, we guarantee resistances exceeding 400 °F.
Another consideration we pay attention to are sound absorbing materials, which are fundamentally important for the reduction of noise and heat, using cartridges manufactured with a range of fabrics (14-micron CE textured). These are specifically conceived for the reduction of noise, particularly at high frequencies, and are capable of withstanding high temperatures.
