Hi guys! I just recently moved to Boston and, other than an upper coolant line that snapped on me and upgraded charge and boost pipes, my car is stock and its time to start building. My first steps are a new intake and catless DP. That said, I have no idea what the emissions regulations are here. Being from California, I am hoping they are more lenient here. That said, I don't want to spend the time and money if I can't get it registered here. Anyone from Massachusetts have any advice on the strictness of emissions here? Thanks in advance!

I don't even think they check emissions anymore. I know they tried like a decade ago but it was a major cluster.

All of the articles about it I've found have been from 2016 or 2017 so I wasn't sure if it was still accurate. Thanks for the info!

They test emissions every other year in Massachusetts during your annual inspection. Generally, most shops don't care what's on your car as long as it passes the emissions test and doesn't have any emissions or safety codes. Not sure if that helps?

MA they plug into the OBD - So a CEL or safety issue you will fail. DP you will fail 💯 you would have to swap out each year FYI Welcome to Boston.

So if they plug into OBD and its not throwing a code itll pass? Or do they still look at it?

Even with a tune that codes out the CEl - with a DP the cats will show not ready and you won't pass… I've tried spacers and j pipes to pass lol only way in MA is put back stock cat, run it for 100 miles and get a sticker…

Thanks for your help! My California tags expire in October, so I might just wait until I get it stickered to get the catless DP. I was told earlier in the thread that they only test emissions every other year, is that accurate?

So if I understand correctly, they do a visual and OBD check? I can tune around the OBD scan, but the visual test will be an issue...

I had to flash my car back to stock to get my smog test to pass my obd2 smog test. I just have BM3 and a stock downpipe
