You can always have some welded in.No cats, would never pass inspection.
My Dakota R/T has been run for 8 years without cats. Only sim boxes to keep the lights on the dash from lighting up, passes the OBD2 test everytime.this makes me wonder how many states do the exhaust sniff test, MA has not done it for years,,, i ran my sliverado for 9 years with out cats and never once did the inspection sta even check to see if i had them,, same with the wifes car and my jeep inspection stations never check for cats.
