Constructed from lightweight high-grade titanium – with complex parts made in Akrapovič’s in-house foundry – the Evolution Line provides a weight saving over the stock system, and increases power and torque throughout the rev range. The Evolution Line (Titanium) has been designed to meet EC/ECE type approval as a plug-and-play system and fits directly onto the BMW X5 M’s stock downpipes. It is tuned to provide a perfect sound accompaniment to the car’s sporty feel, and is perfectly finished with hand-crafted carbon-fibre tailpipes to offer a beautiful visual appeal. The distinctive round design tailpipes have titanium inner parts to make them stand out from the crowd even more. The tailpipes have been impeccably crafted and designed to fit seamlessly with the optional carbon-fibre diffuser. It is also available with the optional Akrapovič Sound Kit.
