Hello board,
We did the famous OEM Exhaust mod to M3post member "ROTURBO"s mint Mineral White E93 M3. I must say this modification sounds amazing, and exotic like. The installation can be done a few ways. Our method was similar to AUTOcouture's method except we did it slightly different.
Here are some pics to show how it happens:
