Featuring a muffler and collector with a resonator made from lightweight titanium and link pipes made of high-grade stainless steel, the Evolution Line (Titanium) exhaust system fits directly onto the Giulia Quadrifoglio’s stock downpipes. The system includes parts cast in the company’s in-house foundry, such as the valve housing and X-part in the muffler, which is perfectly formed to allow exhaust gases to mix at a precisely defined mixing ratio.Developed to deliver both power and torque gains throughout the range and significantly reduce back pressure, it is finished with handcrafted carbon-fibre and titanium tailpipes to enhance the visual enjoyment of the exhaust.In-depth engineering has produced a deep and sporty sound with no unwanted drone, perfectly suitable for everyday use. It is distinctly different from the stock system, especially during partial load, when shifting, and at higher rpms, where it delivers a pure racing sound.The system is a simple plug-and-play operation to fit, and it has been designed to meet ECE type approval. The optional downpipe set and Akrapovič Sound Kit are also available.Because of packaging requirements, the EVO system has been split into two codes. Please be aware that both part numbers (S-AR/TI/1H and E-AR/T/1) must be ordered.EC type-approval is valid for engine type 670050436.
