This sporty elegance makes this Bavarian machine stand out from the rest and offers the taste of a more powerful version, accentuated with the additional power gains and weight losses of the Evolutionperformance exhaustsystem. The dual-mode ECU-controlled valve exhaust from Akrapovič offers stock-level sound at normal cruising, and a joyful deep sporty note when driving the BMW 335i more dynamically.
