Akrapovič exhaust system, manufacturer part number S-AR/TI/6H, for ALFA ROMEO Stelvio Quadrifoglio 2017-2020.

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  Akrapovič Sound Kit is also available. - power +4.5 kWat 6500 rpm - torque +7.6 Nmat 3100 rpm - weight -6.2 kg PERFORMANCE GRAPH INSTALLATION INSTRUCTIONS
