Expert's advice:
For the ultimate in weight reduction, tuning potential, and racing sound, Akrapovič offers stainless steel cat-less downpipes to make the BMW M3/M4 an even more powerful machine. This setup is intended for dedicated track-day cars and enthusiasts, and it will also add to the overall experience of what’s already a stunning performance car for any discerning driver. Delivering great sound, without creating unwanted cabin noise, these beautifully-crafted downpipes offer an upgrade to Akrapovič’s Evolution exhaust system.
When installing Akrapovič aftermarket optional downpipes, which are developed for use on closed tracks only, remapping the ECU is mandatory, in order to prevent potential »check engine light« warning signals.

MOSSELMAN tuning experiences
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!
Dennis - BMW X5 40e
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!
Thom H.
Very happy with my improved car, the car reacts better on the throttle and is very direct. Also, the exhaust sounds better!
Rob 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!
Anders M.
After 1,5 years still very happy with my iTronic. By far the best upgrade I could have done with my BMW 340i.
