This is an OEM replacement rear (bank 2) turbo assembly for the S55 engine in the F8X M2 Competition, M3, and M4. This is a new turbo from Mitsubishi, not a rebuilt unit. This is a complete assembly, including the manifold to the engine and the wastegate. Signs of a failing turbo are high oil consumption and blue smoke from the exhaust (not from a leak or failing CCV system) because the internal oil seals are no longer retaining oil. Without critical lubrication and cooling effects from oil, the turbo shafts and bearings are usually the first to wear and that requires a complete rebuild. You might also see increased turbo lag or failure to hold boost, which is usually a sign of a failing wastegate or some other internal issue. With any internal problems, the turbos need to be replaced. This is a new turbo - No core charge.

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 Sound Kit is a remote control for the valves on the Akrapovic muffler. While the muffler valves are also controlled like the factory valves in Comfort, Sport, and Sport+ modes, the Sound Kit will let you open or close the valves via handheld remote or even from your phone (iOS or Android app). The Sound Kit works with the existing wiring for the Akrapovic system so installation is a breeze.
