Just tried to have my NYS inspection done on the mustang....emissions failed of course looking under the car at the garage relized what I thought was cats was two glass packs or similar type mufflers if you can call them that welded in. Anyone know of any good tricks to get it to pass I did change the PCV valve today as the car was putting out some blue smoke and that cured the smoke issue so maybe that had something to do with not passing since the computer has the O2 sensor and such deleted or set to read ready. My next question will be if I end up having to put cats on it whats a cheap cheap set of 2.5" cats I can buy for the inspection they will most likely be removed after.
