This axle-back exhaust system is manufactured entirely from titanium. This makes this system ideal for cutting weight while being structurally stronger than the OE exhaust system. The engineers at Akrapovic have retained the dual mode exhaust flap control from the original system. This allows the vehicle to have a more civilized, but deeper than stock sound at low speed. However, at higher RPM (or when selecting the S mode on the gearshift) the muffler is bypassed, creating a deep and sporty sound much more in keeping with the personality of the car. The included exhaust pipe tips are made completely from titanium OR a carbon fiber/titanium composite to add a high-end, refined style. Performance has not been left out of the design. The system dramatically reduces backpressure and is an excellent starting point for further engine tuning or turbo modifications. Even when installed on an otherwise stock vehicle a gain of 7.3 horsepower and 17.4 Nm/12.8 lbs-ft of torque are achieved. Furthermore, a weight reduction of 3.0 kg/6.6 lbs. is realized. The OEM catalysts are retained, so no reflashing of the ECU is required and the check engine light will not be triggered. Titanium muffler with integrated exhaust valves Statistics: +7.3 HP (at 4400 rpm) +17.4 Nm/12.8 lbs-ft of torque (at 2350 rpm) 3 kg/6.6 lbs. lighter than stock Not for sale outside the US or Canada.

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.
