Akrapovič Titanium Slip-On Line Exhaust System for G8x BMW M3 & M4

Akrapovič engineers the Titanium Slip-On Line Exhaust System using high-grade, lightweight titanium paired with hand-crafted carbon fiber tailpipes, achieving a weight reduction of approximately 35% compared to the factory system. Featuring dual collectors cast in Akrapovič’s in-house foundry, the system is supplied with a specially developed Akrapovič control kit to deliver a refined and engaging sound profile, producing a rich, subdued tone during cruising that builds into a deep, sporty character under dynamic driving, while maintaining balance and clarity across the entire rpm range. The tailpipes are offered in an innovative octagonal titanium design with a carbon fiber outer sleeve, alongside a classic cylindrical option for a more traditional appearance. Dyno testing on a BMW M4 Competition with a standard exhaust recorded gains of 8.0kW (10.9hp) at 6,000rpm and 13.9Nm of torque at 5,000rpm, with no ECU remapping required.

Slip-On Line

• Featuring two precisely styled, hand-crafted carbon fiber tailpipes that complement the titanium piping, this exhaust system is designed as both a visual and acoustic statement. The sound profile is carefully tuned to match the vehicle’s performance, delivering a distinctive tone and the unmistakable Akrapovič signature sound.

Unparalleled R&D

• The development and production of an Akrapovič exhaust is a fully integrated in-house process. From research and development and sound engineering, through material testing laboratories and the company’s own titanium foundry, to manufacturing, evaluation, and final validation, every stage is completed within Akrapovič’s state-of-the-art facilities.

Only High-Tech Materials

• Akrapovič uses only the highest-grade materials in the production of its exhaust systems. All materials are rigorously inspected upon arrival and evaluated in the metallurgical laboratory.
