This SAC from the M division of BMW is a tour de force. Add the Akrapovič Evolution performance exhaust system for improved power, reduced weight, and better sound. The Evolution is a complete “catalytic converter back system” and comprises titanium link pipes with resonators, a titanium X-pipe, and a muffler with integrated valves. It dramatically reduces back pressure and enhances power delivery....

The tailpipes are the most visible part of the exhaust system, and that’s why we dedicate particular attention to them at Akrapovič. In order to satisfy the most discriminating tastes, we’ve created special titanium-alloy tailpipes. To make our tailpipes stand out from the rest even more, in addition to selecting the finest materials, we also made them larger.
