The M division of BMW unleashed this powerful SUV and now, with anAkrapovičEvolution Line exhaust system, you can experience more power, reduced weight, and a deeper sporty sound. The titaniumperformance exhaustincludes a link pipe set with resonators, an X-pipe, and a muffler with a dual-mode exhaust flap control to reduce back pressure and enhance power delivery. The system improves power delivery, especially in the high and mid rev range. The dual-mode exhaust flap system creates a deeper but civilized sound at low revs and a sportier exhaust note at higher revs, all without droning. Complete the look with a choice of four 100 mmtailpipes in titanium or carbon fibre. Further tuning opportunities exist with our stainless steel high-flowdown pipes.
