Akrapovič Slip-On Line (Titanium) + Carbon Tailpipe Set - BMW 1M Coupé (E82) 2011-2012

M-BM/T/4H + TP-CT/5

Utilizing a single muffler arrangement, the fully titanium Akrapovič Slip-On is designed to be modular. In its basic mode, all exhaust gases flow through the muffler, giving you a deeper rumble of an exhaust note compared to stock without any drone. However, the muffler system is built in such a way that by replacing a blocking plate with the optional Akrapovic sound kit valve system the driver is able to noticeably increase the volume of the exhaust at the press of a button. Once activated, the majority of the exhaust gases route through the muffler bypass outlets. Even when installed on an otherwise stock vehicle, power gains are achieved and weight reduction realized. Complete the look with a set of four exquisite tailpipes in titanium or carbon fibre.

Carbon tail pipe set

The tailpipes are the most visible part of the exhaust system, and that’s why we dedicate particular attention to them at Akrapovič. In order to satisfy the most discriminating tastes, we’ve created handcrafted carbon fibre tailpipes. To make our tailpipes stand out from the rest even more, in addition to selecting the finest materials, we also made them larger.

Akrapovič Sound Kit

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.
