Sorry, unless you have a buddy who works at an emission inspection station and can look the other way, you won't pass the MA visual inspection without the cats.
If you no longer have the original cats I would consider getting a high-flow catalytic converter system. You'll pass emissions and won't lose much power at all.
Walker makes a nice hi-flow set of cats for under $300.
After that, a tune-up, including a new PCV,
stock timing and a clean or new air filter should pass you right through emissions. That, and the outrageous $29. inspection fee, of course.
Oh, and don't be leaking any fluids or have bald tires when you go as they'll fail you for that, too. CT is bad for emissions but the MA regulations are even worse. Of course, if all else fails, you could always move.
Good luck.
