All right y'all, the question you always get when making exhaust changes is how does it sound? With all of the changes to my G87 M2 exhaust line, I wanted to share a full comparison of the mods, side by side from stock to fully changed out.

We are comparing:
1. Fully OEM stock
2. Active Autowerke EL midpipe, OEM back box
3. Active Autowerke EL midpipe plus new axleback back box.

Each stage definitely makes a change and addresses the common concern of the new G8X models being too quiet regardless of what mode you are running in. I did my best to compare equally and from the same distance with the same equipment. The best test is always in person, but this at least gives you an idea of the changes these upgrades can make.

Check it out!

I was a tad surprised to hear the mid with the AB added it was almost a bit quieter with valves open than the mid with the oem box? Or is that just perhaps audio limitations?
