Quanto mais leve é esse escape (se é que é) sabes?
No site da Akrapovic esta é a única informação existente:
The Alfa Romeo booth will have the latest design prototypes and studies for the Italian manufacturer’ stunning new 4C Spider. This featherweight two-seat sports car is one of the most important Alfas in years, and Akrapovič has teamed up to produce a lightweight titanium exhaust system with carbon fibre tailpipes that will increase both power and performance as well as adding that unmistakable Akrapovič sound to an already captivating machine.
Um sistema de escapes para o Abarth 500 fica 2.9Kg mais leve. 3Kg no 4C já é qualquer coisa...
