Default Massachusetts Inspection Question Cobb Exhaust

I should have posted this here.

2007 WRX Cobb Stage 2, with turbo back Cobb exhaust with cat.

Will that exhaust pass Massachusetts inspection? No check engine lights.

I have a 3" Greddy cat back with a 3" catted down pipe, and a catless up pipe on my 05 Legacy GT. I passed no issue last year.

It completely depends on the inspection station. If the inspector is a stickler and knows Subarus and knows it's not a legal cat (legal ones are stamped on 2 sides....MA uses Cal emissions laws), then they could fail you. I have never seen my inspection station look under the car for anything beyond testing the ball joints. They have become more thorough, now that all inspection bays have cameras monitored by the RMV. But still, the inspectors don't want to spend an hour to get a stupid $35 fee.

I passed for a decade with a similar setup, but as Jack mentioned YMMV.

Unless something has changed, MA is emissions and vehicle inspection alternating every year. So you've got the cat drama and catback drama to deal with in any given year. Joy.

Thanks! Was worried about it being louder than OEM.

Annual. They don't test the tail pipe anymore. They only plug into the OBD port.

all they do is take a picture of the plate and the VIN tag and plug into the OBD 2 port...no more tailpipe test. The safety test is still the same..checking for play in suspension and horn wiper and washer, windows, and any rust holes. The visual is not very comprehensive.

I moved out of MA 4 years ago, it was every other year until recently, right?

I think when they had the dyno rollers in the garages, they did emissions every other year. That's gone. At most, they plug into the OBD port, but it's the same every year. For almost a year now, all inspection shops have cameras fed back to the RMV. I've noticed that the inspectors now check everything on the check list. I haven't seen them putting the car on a lift. They might look under the car while checking ball joints, but that's about it.

If your car is tuned you may run into 2 of your sensors not being ready at inspection: o2 and EVAP.

Easy fix: Fill tank to 3/4 pump gas, let car sit overnight. Cold start, idle 4 minutes, then normal drive for 10/15 minutes NOT GOING OVER 55MPH, NOT GOING OVER 3k RPM.

Boom, both EVAP and o2 ready
