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 BMW M5’s stock downpipes. Developed to deliver both power and torque gains throughout the range and significantly reduce the back pressure, it is finished with hand-crafted carbon-fibre tailpipes to enrich the visual enjoyment of the exhaust. The tailpipes have been perfectly crafted and designed to fit beautifully within the optional carbon-fibre diffuser. Optional carbon-fibre mirror caps are also available to further enhance the car's appearance.
