Akrapovic Exhaust System for Alfa Romeo Stelvio Quadrifoglio
Primary Components:
Akrapovic Slip On Line (Titanium) for Alfa Romeo Stelvio Quadrifoglio (S-AR/TI/6H)
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 Stelvio 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 Akrapovic Sound Kit is also available.

Optional Components:
Akrapovic Sound Kit for Alfa Romeo Stelvio Quadrifoglio (P-HF1321)
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With the use of the optional Akrapovic Sound Kit, the ECE type approval is no longer valid.
