Akrapovic 11-12 BMW 1 Series M Coupe (E82) Slip-On Line (Titanium) w/ Carbon Tips

Akrapovic 11-12 BMW 1 Series M Coupe (E82) Slip-On Line (Titanium) w/ Carbon Tips Akrapovic Part Number M-BM/T/4H-C 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.
