Akrapovic Akrapovič Sound Kit Mercedes-AMG GLS 63 (X167) 2020 2023

The optional Akrapovič Sound Kit lets owners of selected Akrapovič car exhausts control the system's sound from the cockpit, switching easily between quiet mode and a sportier tone.

  • A receiver (already included in the evolution system) drives the actuators that open or close the valves at the end of the exhaust
  • Valves are regulated with the Sound Remote Controller

With the optional Akrapovič Sound Kit fitted, the ECE type approval is no longer valid.

AKRAPOVIČ


Where Design and Engineering Become One

Akrapovič is a Slovenian manufacturer of premium exhaust systems for motorcycles and cars, recognised worldwide as the benchmark in high-performance exhaust technology. Founded on a belief that the essence of a great exhaust system lies in the seamless integration of design, materials, and engineering, every Akrapovič product is developed by a multidisciplinary team of industrial designers and engineers working in close collaboration. The brand's signature hexagonal muffler, introduced in 2005, transformed the motorcycle exhaust market, and continuous innovation since has earned Akrapovič multiple Red Dot Design Awards, including the prestigious Red Dot: Best of the Best in 2014.

We Visited Akrapovič! Here's What We Found

Our team travelled to Slovenia for a three-day Akrapovič dealer training, and it was unlike anything we expected. From product sessions covering the latest innovations and sales developments, to hands-on driving experiences in a Porsche 911 GT3, Cupra Formentor, and Toyota GR Yaris, including live exhaust sound demonstrations, to a full factory tour where we witnessed titanium welding firsthand and saw exactly how racing technology transfers into the products we sell.

Sound, Testing, and the Pursuit of Perfection

An Akrapovič exhaust is as much a precision acoustic instrument as it is an engineering product. A dedicated team of NVH engineers analyses every tube, muffler, and tailpipe using frequency-domain sound mapping, dyno testing, acoustic transmission loss measurements, and on-road validation, tuning each system to the specific character of the vehicle it is designed for. Durability is validated on an autonomous motorcycle dyno running exact programmed duty cycles, and new products are tested in partnership with top-level racing teams on circuits worldwide. From the first 3D CAD scan through to final assembly and quality inspection, every detail of every Akrapovič exhaust is accounted for, to the last millimetre.

Materials Science at the Highest Level

Akrapovič's material expertise is what truly sets them apart. Their exhaust systems are crafted from proprietary titanium alloys, three times stronger than commercial pure alloys at elevated temperatures, and 40% lighter than stainless steel — developed and validated in an in-house metallurgical laboratory that monitors chemical composition, hardness, tensile properties, and microstructure at every stage of production. For applications demanding extreme thermal resistance, Inconel super alloys capable of withstanding up to 1,000°C are employed. Carbon fibre components, produced in-house using temperature-resistant composites, weigh as little as one eighth of stainless steel while offering tensile strength up to eighty times greater per unit weight. No other exhaust manufacturer applies this depth of materials science as standard.
