With ECE type approval for the OPF\/GPF-equipped BMW M2 CS, it combines a deeper and more engaging S58 exhaust note with significant weight reduction and measurable performance gains.\u003c\/p\u003e\n\n\u003cp\u003eManufactured from high-grade titanium, the system features two exhaust valves, dedicated acoustic reflectors and titanium components cast in Akrapovič's own foundry. The result is an exhaust that remains refined during normal driving but develops a much deeper and sportier character when the M2 CS is driven more dynamically.\u003c\/p\u003e\n\n\u003ch2\u003eAkrapovič exhaust for the BMW M2 CS G87\u003c\/h2\u003e\n\n\u003cp\u003eThe BMW M2 CS takes the G87 platform considerably further, and Akrapovič developed the \u003cstrong\u003eS-BM\/T\/39H Slip-On Line\u003c\/strong\u003e specifically for this application. The system replaces the factory rear exhaust section while retaining the usability expected from a road-going M2 CS.\u003c\/p\u003e\n\n\u003cp\u003eIts titanium construction reduces exhaust weight by \u003cstrong\u003e7.3 kg, equivalent to a 32.7% weight saving compared with the standard rear exhaust\u003c\/strong\u003e. Two electronically controlled exhaust valves and two acoustic reflectors manage gas flow and sound depending on driving conditions.\u003c\/p\u003e\n\n\u003cp\u003eAt normal cruising speeds, the system produces a smooth and rich tone. Under greater engine load and at higher revs, the valves and acoustic design allow the S58 straight-six to develop a deeper, more purposeful exhaust note.\u003c\/p\u003e\n\n\u003ch2\u003ePerformance and weight reduction\u003c\/h2\u003e\n\n\u003cp\u003eAkrapovič tested the Slip-On Line on a BMW M2 CS with the standard factory exhaust as the reference.
