How many of you are running aftermarket exhaust components, and have you ever gotten crap at the inspection stations because of it? If so, was it over the muffler/noise level, headers, or aftermarket cat?

I have heard people talk about how these aftermarket parts are illegal in MA, and I have heard others say they have had them on forever without incident. Trying to see in which direction the scales tip on this issue.

Am ultimately wondering if I should even bother trying to get my TA w/aftermarket exhaust passed, or just convert back to a stock system before going to the station.

 

As long as your emissions equip. is intact they really shouldn't give you a hard time. At one time I was running Edelbrock TES headers, 3" cat and full 3"
cat back Flowmaster system (with fully functional emissions) on my 89 Formula and never had a problem.

 

it all depends on how much of a **** the inspector wants to be. they can make your life miserable or they can really like yoru car and pass you wihtout checking anything.
