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, Akrapovič 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 Akrapovič’s Evolution exhaust system.

When installing Akrapovič 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.

Those are the resonated (muffler) central pipes of the Evolution Line (Titanium) Exhaust System

(Gains: +6kW @6950rpm, +12.6Nm @2850rpm, -4.1Kg of weight reduction). 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.

(Gains: +9kW @7100rpm, +12.1Nm @7100rpm, -6.0Kg of weight reduction). Constructed from high-grade lightweight titanium and finished with eye-catching handcrafted carbon-fibre and titanium tailpipes – carbon outside, titanium inside – for enhanced kerbside and drive-by appeal, the Slip-On Line (Titanium) has been designed to fit directly onto the Giulia Quadrifoglio’s stock link-pipe. With parts cast in the in-house foundry, such as the valve housing and an X-connection element in the muffler, which is perfectly formed to allow exhaust gases to mix at a precisely defined ratio for perfect flow, the exhaust has been designed to deliver both power and torque gains throughout the rev range. Unwanted drone has been eradicated through in-depth engineering to produce a deep and sporty sound, which is ideal for everyday use, and this also provides acoustic feedback to the driver – to know and feel which rpm the car is being driven at, and when to shift gears for optimum aural enjoyment and performance. This makes for a linear and smooth sound in partial load when shifting gears, and at higher rpms the Slip-On Line (Titanium) delivers a racing sound with added higher engine harmonics.

The system is a simple plug-and-play operation to fit, and it has been designed to meet ECE type approval. The optional Akrapovič Sound Kit is also available.
