Akrapovič for Alfa Romeo Stelvio Quadrifoglio
Akrapovič develops materials, construction and sound as one complete exhaust system. Its development work refines both gas flow and acoustics, with demanding cast components produced in the in-house foundry. Futurez has proudly served as an Akrapovič importer for more than a decade.
The high-grade titanium silencer connects to the vehicle’s original link pipes. A cast valve housing and X-connection in the muffler manage exhaust-gas mixing and flow. Hand-crafted tailpipes combine carbon-fibre outer sleeves with titanium inner sections. The sound is deep at low engine speeds, smooth at partial load and brighter at higher revs. The acoustic design also considers passenger comfort and the reduction of unwanted cabin drone.
Package contents and choices
The main manufacturer product code is S-AR/TI/6H.
Tailpipes shown for the complete system are included. Optional Sound Kit selection is priced separately in the package choices where offered.
