Having home-court advantage to Akrapovic's facilities, we work very closely with the company and were able to provide installation and collect some data on the new Evolution systems on the F8X M3/M4 platforms. Akrapovic's newly-acquired M4 was just completed from getting wrapped and needed a system installed right away.
Akrapovic released just a handful of systems on late last week. With EAS being an authorized Akrapovic dealer since their introduction to the US, we were able to get one of the first systems for our M4 as well as installing the system on Akrapovic's own M4.
We'll be installing the following items in this thread:
- Akrapovic Evolution Exhaust System w/ carbon fiber tips
- Akrapovic Carbon Rear Diffuser
Akrapovic Evolution Exhaust
As expected from Akrapovic, the systems are very high quality and constructed from full titanium. Everything needed is included with the Evolution systems for a bolt on installation. For those utilizing the Slip-On systems, the OEM exhaust is cut and installed with the provided clamps.
Valvetronic
Electronic Bypass valves are retained from the stock exhaust system on the Akrapovic silencer.
Optional Carbon Fiber/Titanium Exhaust Tips
There are two options of exhaust tips: Carbon Fiber/Titanium or Full Titanium. For this install, we will be installing the hybrid Carbon Fiber/Titanium Tips.
Akrapovic Diffuser
Relatively new for the BMW scene, Akrapovic has been manufacturing carbon for some time now of other platforms such as the GT3 and Ferrari lines. The quality on this piece is no different. With a matte finish, this is a beautiful piece with exceptional quality, matching the tips nicely.
Weights
BMW has taken a much different approach with the 5th Generation of the M3 (and M4) models concentrating on vehicle weight.
OEM Exhaust Weights
Full System: 69lbs
Akrapovic Exhaust Weights
Slip-On Section/Silencer: 29.5lbs
Connecting Pipe: 14.0lbs
Combined Weight: 43.5lbs (25.5lb weight savings over OEM)
Exhaust Note
The sound has a very throaty exhaust note, very exotic while retaining the S55's signature sound. When mashing on the throttle, it seems to come alive ready to punch on anything in its way. Not overbearing, yet aggressive in nature.
