Rear O2 sensor ???????
Mike, not sure what the requirements are in MA...what year your car is & what kind of changes you've done.
If they don't do a visual inspection, and the tune is very good, you should pass the sniffer portion of the test, even without the rear o2.
Hello to Granville. We used to hike on the 'mountain(s)' just about every weekend! from CT
