Akrapovič Alfa Romeo Giulia Quadrifoglio Slip-On Exhaust System
Constructed from high-grade lightweight titanium and finished with striking handcrafted carbon-fibre and titanium tailpipes – carbon on the outside and titanium on the inside – for enhanced kerbside and drive-by appeal, the Slip-On Line (Titanium) is designed to fit directly onto the Giulia Quadrifoglio’s stock link pipe. With components cast in the in-house foundry, such as the valve housing and an X-connection element within the muffler, which is precisely engineered to allow exhaust gases to mix at an exact ratio for optimal flow, the exhaust system is crafted to deliver power and torque gains throughout the rev range.
Unwanted drone has been eliminated through meticulous engineering, producing a deep and sporty sound ideal for everyday driving. This also provides the driver with acoustic feedback to sense and feel the engine’s rpm, and to know exactly when to shift gears for the best aural experience and performance. The result is a linear and smooth sound during partial load gear shifts, while at higher rpms, the Slip-On Line (Titanium) delivers a racing-inspired sound with added high-engine harmonics.
The system is easy to install with a simple plug-and-play operation, and it has been designed to meet ECE type approval. The optional Akrapovič Sound Kit is also available.
