Ready for some amazing exhaust sound? The folks over at Akrapovic show us once again why their exhaust system is rated as one of the best in the world. In a short video, the BMW 1 Series M Coupe equipped with the Akrapovic Evolution exhaust system is taken onto the race track for some drifting sessions and sound heaven.
Akrapovic offer two systems for the BMW 1M: a “slip on” axle back and the Evolution with down pipes and manifold. The latter adds 15 horsepower and 19 Nm of torque, as well as shaving 16 kilograms.
This “cat back” exhaust system is manufactured entirely from titanium. One of the most important changes is the incorporation of link pipes in the system. The inclusion of the link pipes increases low to mid-range power while at the same time producing a deeper exhaust note that the original system lacks. Additionally, a pair of resonators are added to eliminate any chance of in-cabin droning. The mounting flanges are made of cast titanium from our in-house foundry and ensure a perfect, leak-free fit.
Moving to the muffler section of our system, we have an optional wireless “dualmode” exhaust flap control. This allows the vehicle to have a more civilized, but deeper than stock sound at low speed. However, when the exhaust flap is opened the muffler is bypassed, creating a deep and sporty sound much more in keeping with the personality of the car.
Two exhaust tail pipe options are available; The first is made completely from titanium while the other is crafted from a carbon fiber composite. The carbon fiber version was developed on the MotoGP Safety Car, which is driven at sustained high speed, to guarantee uncompromised durability.
In the US, the Evolution exhaust system sells for around $5,800.
