Akrapovic Slip-On Line (Titanium) - BMW M4 (F82, F83) OPF/GPF 2018+

£2101
E-BM/T/6
The Evolution link pipe set upgrades the Slip-On system to the Evolution system, which consists of a slip-on rear muffler and larger Evolution link pipe tubes with a middle muffler, all designed to make the performance and workmanship of the complete system as perfect as it looks. It is crafted entirely from titanium. The whole system is designed to provide the smoothest flow. The power and torque gains of the M4 with the combination of the Slip-On Line system and Evolution link pipe set are guaranteed. In-depth engineering has produced a unique sound profile, distinctly different from the stock system, yielding a deep and sporty sound with no unwanted overtones or drone and an almost racing sound, as well as a significant change to the sound with the valves in the open or closed positions.

The control kit to optimize the balance between sportiness and comfort is included, together with the receiver and Sound Remote controller (or smartphone app) to regulate the valves.

P-HF1194
The optional Akrapovič Sound Kit enables owners of selected Akrapovič car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovič technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller or the new smartphone app (for iOS and Android) to regulate the valves.

Akrapovič Sound Kit P-HF1194 is developed for use with Slip-On Line (Titanium) only. If upgrading the slip-on system with evolution link pipe, specially developed Akrapovič Sound Kit is already included within the evolution link pipe set.

£1045
DI-BM/CA/4/M
Beautifully crafted hand-laid high-quality carbon fibre diffusers are perfectly styled to enrich the Akrapovič tailpipes and the rear of the car. The sporty and aggressive design adds an extra dimension to the whole package and shows the exhaust system off to its best. Available in high-gloss or matte finish.

DI-BM/CA/4/G
For vehicles with the base Porsche exhaust system, which is then replaced by the Akrapovič Evolution Line system, the Middle Valve Actuator Kit (P-HF1170) is a mandatory upgrade. If the Evolution Line system replaces the Porsche sports exhaust system, the Middle Valve Actuator Kit (P-HF1170) is not required.
