Akrapovic Slip-On Line (Titanium) for BMW 1M with Carbon Tailpipes
Description
Utilizing a single muffler arrangement, the fully titanium Akrapovic 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 realised.
