The right exhaust system can completely transform your driving experience. From the track-tuned precision of Akrapovič to the valvetronic versatility of Stone Exhaust, these systems offer more than just sound—they deliver identity. Let’s explore which brand aligns with your driving goals.
Founded in 1990 by former motorcycle racer Igor Akrapovič in Slovenia, Akrapovič quickly built a reputation in the MotoGP and World Superbike scenes with its high-performance titanium systems.
Their ability to produce titanium components in-house set them apart early on. By 2010, Akrapovič expanded into the automotive space, developing exhausts for elite car brands like Audi, BMW, Porsche, and Lamborghini.
Their systems are developed using motorsport data, wind tunnel testing, and cutting-edge acoustic modeling to ensure both peak performance and refined sound.
Established in 1998, Stone Exhaust has focused on technologically advanced exhaust systems, most notably with their Valvetronic systems, which allow for user-controlled sound levels.
Their exhausts often feature high-grade T304 stainless steel with optional titanium tips and are designed using 3D scanning to ensure a perfect OEM fit. Stone Exhaust also developed the Eddy Catalytic system, balancing emissions compliance with performance gains.
Their emphasis on adjustability and tech-forward design makes them a popular choice among daily drivers and tuners alike.
