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 Quadrifoglios 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.
