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.

MOSSELMAN tuning experiences

  • 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!

    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!

    Visited Mosselman on May 24th for the chip tuning of my 135i, great result! The adjustment is great, when will you post the photo on FB :)?

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