Genuine BMW G87 M2 M Performance Titanium Exhaust System & Diffuser. 1x 18.30.5. 1x 51.12.5. B54 REAR DIFFUSER M EXHAUST. 4x 18.30.5. A86.350 EXHAUST TIP BRONZE. From the racetrack straight to the road: the lightweight valve exhaust system with a titanium rear silencer generates a highly emotive sound redolent of racing sports. It has been specially developed for M models. In optical terms, the titanium tailpipe trim module (consisting of four centrally positioned tailpipe trims) give the car an unmistakable, completely new look. The M Performance silencer system gives the rear of the car a striking and individual appearance. The perforated inner pipes represent the ultimate in high tech and sportiness, accentuating the individual characteristics of the BMW M. Sounds like performance: The Motordynamic button can be used to enable multiple modes to influence the performance of the exhaust system. Sport and Sport+ mode: extremely emotional sound, very sporty, very loud, maximum performance. Efficient mode: sporty sound, significantly sportier and more emotional than the standard system, but with residual comfort for uncompromising everyday use. The silencer system is made from a high quality material mix. The front pipes are made from lightweight stainless steel, while the rear silencer is made entirely from titanium. Lightweight: The silencer system is over 30 % (around 8 kg) lighter than the standard component. The silencer system was developed using the very latest CAD and FEM technology. This ensures a perfect fit and superlative manufacturing quality. Simple installation: The silencer system can be installed easily by bolting it into place. No welding is required.
