A guy in my office just got quoted over $5k to replace his cats on a 750iL (m73/m73n).

Anyone know of a shop in Boston area that can do this job for less than the stealership quote? I've heard that OEM is the way to go and you have to replace all 4 o2 sensors...

Any help would be much appreciated!
