The latest addition to the BMW M series, the impressive M3/M4, delivers outstanding performance that can be further enhanced with the addition of an Akrapovič Slip-On exhaust system. Constructed from titanium, with specific components crafted in Akrapovič's own foundry, this system boasts larger pipes compared to the stock exhaust, resulting in reduced back pressure and increased power, especially at lower RPMs. Featuring a completely new design, it contributes to weight reduction and delivers added power while producing a sporty sound meticulously engineered to enhance lower frequencies for an immersive auditory experience. The heightened power and torque contribute to an enhanced driving experience, complemented by improved agility. To elevate the visual appeal, the Slip-On system offers the choice of titanium or carbon tailpipes and an eye-catching carbon rear diffuser. Vehicles equipped with Akrapovič exhaust systems benefit from significant performance enhancements and heightened responsiveness, experiencing substantial increases in power and torque across the entire RPM range. All Akrapovič exhaust systems undergo precise measurements using computer-controlled flowbenches.
