Akrapovic Exhaust System for Alfa Romeo Giulia Quadrifoglio

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 Akrapovic 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.

Downpipe Set w/o Cat (SS) was tested and developed together with Slip-On Line (Titanium) system or Evolution Line (Titanium).

For the ultimate in weight reduction, tuning potential, and racing sound, Akrapovic offers stainless steel, cat-less downpipes to make the Giulia Quadrifoglio an even more powerful machine. This setup is intended for dedicated track-day cars and enthusiasts, and it will also add to the overall experience of what’s already a stunning performance car for any discerning driver. Delivering great sound, without creating unwanted cabin noise, these beautifully-crafted downpipes offer an upgrade to Akrapovic’s Evolution exhaust system.

When installing Akrapovic aftermarket optional down pipes, which are developed for use on closed tracks only, remapping the ECU is mandatory, in order to prevent potential »check engine light« warning signals.

Fitment notice: Optional downpipes only fit to vehicles with engine number ≥5074. For vehicles with lower engine numbers, additional adapter P-X227 is needed.

THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.

Fitting kit for mounting the optional downpipes to vehicles with engine number ≤ 5074.

The optional Akrapovic Sound Kit enables owners of selected Akrapovic car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovic technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver (already included in evolution system) to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller to regulate the valves.

Akrapovic Sound Kit is also compatible with cars equipped with Alfa Romeo first fit or accessory Akrapovic exhaust.

With the use of the optional Akrapovic Sound Kit, the ECE type approval is no longer valid.
