Akrapovic Exhaust System for BMW M4 (F82, F83) OPF/GPF

Constructed from lightweight high-grade titanium – with complex parts made in Akrapovic’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-fibre tailpipes to offer a beautiful visual appeal. To set off the system to its visual best, optional carbon-fibre diffusers and mirror caps are also available.

The optional Akrapovic Sound Kit (P-HF1194) is also available. If upgrading the slip-on system with evolution link pipe, the optional Akrapovic Sound Kit P-HF1194 is not needed - specially developed Akrapovic Sound Kit is already included within the evolution link pipe set. With the use of optional Akrapovic Sound Kit, the ECE homologation is not valid anymore.

For installing the slip-on system, the stock exhaust system has to be cut. Please read the instructions carefully before the start of the installation.

The Akrapovic Evolution and Slip-On line exhaust systems can be further enhanced with an optional hand-crafted carbon fibre rear diffuser. Developed by Akrapovic’s Design Department, this stunning diffuser, crafted from materials developed through Akrapovic’s racing involvement, is designed to perfectly fit the lines of the unique tailpipes of the Slip-On or Evolution systems, as well as complement the sleek and sporty shape of the BMW.

When mounting Akrapovic rear carbon fiber diffuser BMW comfort access system will not work.

Beautifully crafted hand-laid high-quality carbon fibre diffusers are perfectly styled to enrich the Akrapovic 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.

Diffuser also fits to M3/M4 CS (Sport Club) and GTS version.

Evolution Link Pipe Set (Titanium) was tested and developed together with Evolution Line (Titanium).

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.

When installing the Akrapovic Evolution link pipe set, remapping the ECU is mandatory in order to prevent potential “check engine light” warning signals.

The optional Akrapovic Sound Kit enables owners of selected Akrapovic car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovic 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 to regulate the valves.

Akrapovic 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 Akrapovic Sound Kit is already included within the evolution link pipe set.

With the use of the optional Akrapovic Sound Kit, the ECE type approval is no longer valid.
