Akrapovic Slip-On Titanium Exhaust System Carbon Fiber Tips BMW F80/82/83 M3/M4 | AR Motorwerkz

Product Details

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 crafted from a carbon fiber/titanium composite. The carbon fiber version was developed on the MotoGP Safety Car, which is driven at sustained high speed, to guarantee uncompromised durability. These give the exhaust a little more of an aggressive styling.

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.
