If you don't get caught on the visual you will pass with flying colors. "Somebody" I know passed the CA dyno emmisions test (15 and 40 mph) with no main cat. HC were up, but still like 20% below the failing limit. (FWIW, even though the car passed it was putting out avg. emmisions comparable to the 1977 vintage average.)
That car now has a new main cat with just the pre cats done, mainly to be kinder to the environment.
97 SE MTX, KKM, UR UDP, 19# Injectors, SVT TB, SVT UIM, SVT Flywheel, Grizzly Street Clutch, Upgraded motor mounts, mystifed precats, brand new main cat, SVT exhaust sans resonator, 205-55-15 Dunlop SP5000's 154hp / 156 tq before the SVT exhaust, SVT dual honed upper and swapping the mystery main cat for mystery precats.
