Exhaust specialist Akrapovic has just released their latest titanium exhaust for the Mercedes-AMG C63 which includes a new three valve system and features the latest active-x connection. The aim is to make the exhaust sound like it has more displacement than the 4.0-litre V8. Thanks to adjustable flaps in the tail pipes as well as a flap in the X connection the driver can chose between three different sound levels and styles. Most performance exhausts come with flaps nowadays but they usually have only two options: open or closed. By being able to play with the speed of opening / closing the flaps and adjust the percentage of opening and closing in combination with an additional flap in the X where the left and right exhaust pipes cross, Akrapovic is able to create multiple sound profiles that can be enabled with the driving profiles of the car or the Akrapovic remote. Not only did it take 8 months to develop but the system is a whole 13kg lighter than the stock AMG exhaust and gives you an extra 8 horsepower and 28 Nm of torque.
