The very essence of the product is in the Akrapovic design.
Every component of an Akrapovic exhaust is carefully designed and constructed by a highly skilled multidisciplinary team of designers, engineers and architects. They successfully take on daily challenges, combining a technical solution with an attractive, modern and state-of-the-art design. Its signature hexagonally shaped muffler took the world by storm when it was introduced to the motorcycle market. Its new conically shaped muffler represents the next level of evolution, providing a sharper racing sound and faster acceleration. More is yet to come. Stay tuned.
Newly developed and handmade products are tested on the most challenging race tracks around the world in partnership with dozens of top-notch racing teams. The development process of a prototype starts with a 3D scan of the reference car underbody. The defined 3D coordinates and exact boundaries of the space provided for the exhaust system help develop and optimize the exhaust system layout. Its design is evaluated and optimized to meet the needs of world racing champions.
Further testing ensures better resonant sound, faster acceleration, and eco-friendliness of its exhaust systems.
Using 3D CAD/CAM support, a 3D scanner arm, and CAE simulations combined with measurements, Akrapovic exhaust systems are evaluated and optimized in terms of structural rigidness, fatigue, and thermal loads. Mechanical simulations optimize and define the reshaping process of special titanium alloys and help find the material reshaping limit.
Scrupulous attention to chemical compositions and gas content of titanium, stainless steel, and aluminum alloys is constant; gas content is crucial for the quality of cast titanium parts. Hardness and micro-hardness measurements, tensile properties, plastic properties and formability determinations are carried out for all incoming and new materials by a team of highly skilled engineers. Such regular procedures ensure the best quality of the final product and the use of the best materials.
All major material properties are checked and evaluated in Akrapovic state-of-the-art metallurgical laboratory; it also offers support for the titanium casting facility and production and R&D activities.
Regular monitoring and ongoing evaluations of new advanced materials on the market ensure higher quality standards for the end products.
Chemical compositions and gas content of titanium, stainless steel, and aluminum alloys are controlled. Controlling gas content, especially in titanium castings, is crucial for the quality of cast parts.
Hardness and micro-hardness measurements, tensile properties, plastic properties, and formability determinations are performed regularly for all incoming and new materials, so the quality and the use of the most appropriate materials in various applications and products are guaranteed.
Complete metallographic sample preparation for defect crack checking, microstructure checking, and weld quality evaluations ensures better understanding of the materials and helps to better control technology processes and parameters such as welding, bending, forming, casting, etc.
Some other important material properties (oxidation resistance, high temperature properties, coatings, etc.) are evaluated in cooperation with various European universities and research institutes.
In the Akrapovic measuring laboratory, prototype, exhaust system, and cast part measurements are carried out with a Zeiss Contura scanning machine, a GOM Atos IIe measuring camera, a Romer Sigma scanning arm, and other ultra-precision measuring equipment.
Measurements on motorcycles and cars are performed with the Romer mobile scanning arm.
For the most accurate 3D measurements, the Zeiss CONTURA G2 CMM coordinate scanning technology with a scanning area of X = 1000 mm, Y = 2100 mm, and Z = 600 mm is used.
For measuring, quality control, but mostly for reverse engineering the Atos optical system is used; it enables the digitalization of even the most complex shapes in an exceptionally short period of time. The system offers a very clear comparison between a mathematical model and the product measurements. The measuring camera records 1.4 million data pixels per second.
A team of engineers spends countless days looking for the perfect sound, one of the four major elements of the exhaust system design. On one hand, the exhaust system must fulfill the homologation noise levels, on the other hand, a good exhaust system is expected to deliver better and appreciated sound that you want to be recognized by. At Akrapovic, special measurement techniques and equipment are used to capture and analyze cabin and tailpipe exhaust sound, which is presented in a sound color map – a signature of the exhaust system. Based on results, proper acoustic elements are calculated.
At Akrapovic, special measurement techniques and equipment are used to capture and analyze the cabin and tailpipe exhaust sounds. Computational process order tracking takes short periods of sound signal and analyzes it in the frequency domain for all available rpm data, which are combined into a matrix called a “sound color map” that represents a signature of the exhaust system and the car. This process helps extract sound content and present it in a 3D graph.
This process helps engineers find the sound characteristics of the exhaust system. Sound measurements can be performed on the road or on the dynamometer.
Furthermore, a sound transmission loss measuring device developed in-house is used to measure the effectiveness of several acoustic elements for the muffler.
State-of-the-art-isolated chambers and high-tech measuring equipment allow for the precise development of exhaust systems that meet even the strictest noise emissions regulations.
From development to production, you can see the precision that goes into making each new exhaust system. This is further underscored by close business relationships with suppliers of titanium and other materials that are used in the production of exhaust systems. At the Akrapovi? metallurgical laboratory with the latest equipment, the company checks and assesses all major material properties and offers support to the titanium casting facility, production and R&D activities, ensuring final products of the finest quality.
Great ideas need to be brought to fruition in a great and state-of-the art product. The production process makes this possible. It is a synthesis of expertise from various engineering spheres such as forming, welding, assembly processing, bending, modern CNC machining, controlling, and many others. The basis for everything is proper tooling. It is the key to success. The company boasts an in-house tooling design and a tooling workshop, so it is able to design and produce unique tools and jigs. Furthermore, Akrapovi? has over 20 years of experience in using titanium alloys for exhaust system applications, which shows in every product.
In the constant search for the latest technology solutions, many advanced processes have been introduced to Akrapovic production: the hydroforming process for tube forming, using a medium based on water emulsion with lubricant additives, is just one of many. The introduction of this technology allows the complete realization of technological ideas that are developed by Akrapovic R&D. One such idea is the patented D-type header tubes, which until now have been manufactured through other production processes.
Titanium casting brings the company to the highest technological level and offers complete freedom in product design. The titanium foundry facility participates in all phases of the investment casting process, from the wax injection to the final inspection of the cast parts with X-ray radioscopy and other control procedures (chemical analyses, mechanical properties, dimensional accuracy, etc.).
Akrapovic production consists of advanced and unique welding techniques, which have been upgraded specifically for titanium specifications. Furthermore, an in-house tube production process offers freedom in diameter choice and wall thickness as well as material selection.
The modern carbon-fibre composite parts facility makes the production of all kinds and shapes of composite parts possible.
