Expert's advice:

The Akrapovič Slip-On exhaust system is made of proprietary titanium and consists of completely newly developed, split-end mufflers. This system significantly reduces the overall vehicle weight and delivers extra power and a sporty sound. The power and torque increases are a joy to experience with improved agility throughout the entire rpm range. The improvement of the car’s acoustics provides the perfect soundtrack: the Akrapovič exhaust system amplifies and enhances the beautiful sound of the eight-cylinder motor, without any droning. Complete the look with a set of two exquisite tailpipes in titanium or carbon fiber.

Note: The tailpipes are NOT included and have to be ordered separately!

MOSSELMAN tuning experiences

  • Dennis - BMW X5 40e

    My first impressions after the remap: the acceleration is much more dynamic, it feels like the car now has the powertrain that fits it well! I’m very satisfied with your service, explanations, and friendly approach. Thank you!

    Mosselman tuned my BMW 318d today. What a result, it became a completely different car! Very professional company and friendly staff. This was my second car here and again they have exceeded my expectations. Thanks!

  • Rob M.

    Very happy with my improved car, the car reacts better on the throttle and is very direct. Also, the exhaust sounds better!

  • Anders M.

    With Mosselmans' performance package I exceeded even more than the company advertised on their website! The information-sharing process was easy and hassle-free. Excellent customer service from Leon and his team!

    After 1,5 years still very happy with my iTronic. By far the best upgrade I could have done with my BMW 340i.
