The exhaust is paired with the S58 engine, which is specifically enhanced by the BMW M division using the B58 unit as starting point. The straight-six petrol engine is offered in two output stages. The entry-level M3 and M4 models receive the 353 kW / 480 PS (473 hp) iteration of the powertrain, whereas the range-topping Competition versions are powered by the 375 kW / 510 PS (503 hp) version of the S58 unit.
Power delivery is performed either via six-speed manual gearbox or an 8-speed M Steptronic transmission with M Drivelogic management unit. The output essentially reaches the rear-axle wheels for both the 480 PS and the 510 PS Competition variants. There is no pricing available yet, but considering the previous M Performance Exhausts sell for over $2,500, we expect a similar or even higher price point. The new M Performance Parts, along with the exhaust, will be available from market launch this Spring.
