The Akrapovič Evolution Line is a full, high-performance exhaust system that combines the Slip-On Line with the Evolution Link Pipe, forming one of the most refined and powerful exhaust solutions available for the G8x M3/M4 platform. Crafted entirely from premium-grade titanium, it delivers extreme weight reduction, exceptional flow efficiency, and an unmistakable, motorsport-inspired sound.

The Evolution Link Pipe — available in stainless steel or titanium — unlocks the full potential of the S58 engine, increasing power, torque, and acoustic intensity across the entire rev range. Compared to the OEM setup, the system provides sharper throttle response, improved mid-range punch, and a deep, aggressive tone that escalates dramatically under load.

The exhaust is finished with hand-crafted carbon-fiber tailpipes in the new octagonal design or the classic cylindrical style. The integrated Akrapovič Control Kit gives full authority over the exhaust note, from a refined and subdued sound in comfort driving to a raw, track-bred roar when fully opened.

Optional upgrades:

• Track-use downpipes

• Akrapovič Sound Kit

• Hand-crafted carbon-fiber rear diffuser
