Description
Looking for the best exhaust system for BMW M4?
Constructed from lightweight high-grade titanium – with complex parts made in Akrapovič’s in-house foundry – the Slip-On Line provides over 45% weight saving over the stock system.
It is fully ECE compliant. The system is tuned to provide a perfect sound accompaniment inside as well as outside the car's cabin and is perfectly finished with hand-crafted carbon fiber exhaust tips to offer a beautiful visual appeal.
To set off the system to its visual best, optional carbon fiber diffusers are available.
Some images show optional rear diffuser that is not included.
The optional Akrapovic Sound Kit (P-HF1194) is also available.
If upgrading the slip-on system with evolution link pipe, the optional Akrapovič Sound Kit P-HF1194 is not needed - specially developed Akrapovič Sound Kit is already included within the evolution link pipe set.
