If you fail, you need to come back with receipts showing something was done to try and fix the car. I would suggest putting a real muffler in like the LM2 or a Borla in place of the LM1. Then you can swap it back if you want. The LM1 is not a street legal muffler. A resonator is not a muffler, it's an echo chamber. For comparison, some of the early Camaros came with dual resonators and the crossflow muffler. I went through inspection at the Rt1 Lawrence station and my car passed with longtubes, dual cat y-pipe and Random Tech cat-back. But my car has a muffler so it idles quieter than the LM1. I doubt any of the dmv inspection stations would pass it if it's inside the building. If any of the dmv inspections stations have outside lanes, that's where you would have your best chance.
