posted a complete write up and my final comments/observations after getting the OEM exhaust mod done this week. The car is so much fun to drive now, i find myself opening the windows just to hear it

All work done by PsychoChrome in Hollywood.

By far the only shop I contacted who 1. even knew about the mod 2. opened on a Sunday so i could drop off the exhaust and 3. had the work completed in 2 days as promised.
...hit me up at the next bmw meet to hear it and drive
