Just moved to Boston from Chicago and after going to the MA state inspection, was told my car needs to be returned to stock and needs to go to a Motorist Assistance Center (MAC) for inspection.

Wondering if anyone's had experience with this and/or recommend any independent repair shops around the Boston area that would assist with this?

I have the Cobb Stage 2 power package installed on a 2011 135i
  • FMIC
  • Charge pipe
  • Axle-back exhaust
  • Cobb Stage 2 tune

From what I've read so far, seems like I'll need to go back to stock exhaust and stock tune.

Any help is greatly appreciated.
