The Akrapovič Slip-On Line (Titanium) for the BMW F97 X3M and F98 X4M is a lightweight, high-performance exhaust system crafted from premium titanium. Featuring two pairs of titanium–carbon-fibre tailpipes and valve housings cast in Akrapovič’s own foundry, this system blends engineering precision with striking visual presence and a signature exhaust note.

Tuned specifically for the turbocharged inline-six engine, the Slip-On delivers a richer, more engaging sound with increased volume sensation and zero unwanted drone. ECE compliant, it provides measurable gains in power and torque across the entire rev range when compared to the stock M Sport exhaust. Thanks to state-of-the-art materials, the system is 9.5 kg lighter than OEM.

Optional upgrades include the Akrapovič Sound Kit. When it is installed, ECE approval is no longer valid.
