Expert's advice:
Constructed from lightweight high-grade titanium alloys and finished with two sets of carbon-fiber or titanium tailpipes, the system features complex parts crafted at the in-house titanium foundry, including the housing of the valves and collectors from the central muffler to the tailpipes. Two valves – one on each side of the muffler – tailor the gas flow to help produce that unmistakable Akrapovič sound, which is distinctly different from the M8 with a stock system. The exhaust tone is most noticeable as you move through the gears and accelerate, and this can be further controlled through the addition of the optional Akrapovič Sound Kit to provide increased aural pleasure. Akrapovič has achieved power gains of 14.3 hp at 5,200 rpm and torque increases of 19.4 Nm at 5,200 rpm when tested on the Akrapovič dyno against a BMW M8 Competition with a stock M Sport exhaust system for comparison. There is also the opportunity for further exhaust tuning through the addition of the optional Evolution Link pipe set (Titanium); using the link pipe set will change the gas flow and deliver the best sound possible from the Slip-On Line (Titanium).
With the installation of the Evolution Link pipe set, ECE type approval for the Slip-On Line (Titanium) exhaust system is not valid, and remapping the ECU is mandatory when it is fitted.
Note: The stock exhaust system has to be cut to install the Slip-on Line. Please read the instructions carefully before starting the installation.

Proven BMW 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.
