The down pipes are catless, however, that is the extent of information released. Akrapovic is playing them pretty close to the chest. Also, the pricing is expected to double on any new down pipe order.

You can get just the slip-on with the wirelss kit.

All the name brand DP's would fit the 1M, no problem. AR has been the best in quality and fitment so far.

1M Akrapovic systems are starting to ship this week. Contact your local dealer!

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

If not for the hilarious preliminary hard facts, certainly for the blatant marketing inaccuracy:

Current website Numbers (Akrapovic Technical Data) all based on evolution system:
Power +10.5HP (preliminary hard fact: +15HP, inaccuracy 43%)
Torque +16.1Nm (preliminary hard fact: +19Hp, inaccuracy 18%)
weight -8.7kg (preliminary hard fact: -16kg, inaccuracy 84%)
