Hi guys, two dynos.

Engine power Stock vs tuned + Akrapovic Evolution with downpipes

Original: 367PS, 540Nm
Tuned + Akrapovic: 422PS, 585Nm, gain 70PS at 6350rpm, 65Nm at 4660rpm

Wheel power Tuned Stock Exhaust vs Tuned Akrapovic Evolution with downpipes

Tuned stock exhaust: 355WHP, 500Nm
Tuned Akrapovic: 368WHP, 510Nm, max gain approx 15PS, 20Nm

Real figures might defer a little bit, while I got those from the chart and not actual numbers. But you could get the idea of the gain
