Built from high-grade lightweight titanium to reduce weight, with valve housings cast in the in-house foundry, the Evolution Line (Titanium) exhaust system fits directly onto the X6’s stock downpipes. Developed to deliver both power and torque gains throughout the range, it is finished with integrated hand-crafted carbon-fibre tailpipes to enrich the visual enjoyment of the exhaust, styled with a distinctive round design with titanium inner parts to enhance the rear of the BMW X6 M. The tailpipes have been perfectly crafted and designed to fit beautifully within the optional carbon-fibre diffuser. The system is a simple plug-and-play operation to fit, and has been designed to meet ECE type approval. The optional Akrapovi? Sound Kit is also available.
