Exhaust system development
Designing of the performance exhaust system
The development of a performance exhaust system is determined by the characteristics of the engine. The other crucial factors that influence the design are the specific conditions of its use. When developing performance exhaust system that fits all race performance requirements we rely on fluid dynamics theory, performed measurements and most of all our own experiences.

The first step in the designing of the exhaust system is the digitalization of the geometry with a 3D scanner. The goal is to »capture« the geometry of the engine and surrounding components. Than the virtual exhaust system can be designed in 3D, which represents the base for further simulations and prototype production. With our own rapid prototyping technology we are able to build 3D exhaust system prototypes in matter of hours. These models are our starting point as they can be used for fitment checks and welding jig construction.
We know that design maters. That is why we shape the lines of the muffler and tubes in such a way that they reflect sport aggression.
Advanced measurements
Rapid prototyping allows us to perform preliminary flow and acoustic measurements. In this case pressurized air is being used. That enables us to study different effects such as flow rate, back-pressure etc. We carefully study the acoustic properties with the use of the noise generator. This know-how is the result of our own research and development and gives us an unique advantage over the competition.
We use our own tubes for the manufacturing of exhaust systems. For that purpose we have developed a special thin-wall tube production machine. The resulting tubes have very thin walls that allow us to build extremely lightweight exhaust systems. In this case the tube thickness is
A CNC tube mandrel bending machine allows us to produce quality bens. The machine is ideal for custom performance exhaust system production since it enables a very fast tool change. The racing exhaust system is assembled with different tube cross sections so an easy and fast tool change is crucial for a quick development response.
We have developed our own dynamometer and electronics which allow us to measure performance - both on the road and on the stationary dyno. Measurements made on the road give us a realistic effects of the dynamic air induction and cooling effects. As stationary dyno measurements show when the vehicle is connected to the inertia rolls which represent the acceleration mass. Also measured is the power and torque the air-fuel ratio, pressure and the temperatures. The final result is a fine-tuned performance exhaust system.
