my Chevy Nova does not have a catalytic converter, only a muffler at the back. my question is will i be required by law to put one on to pass inspection in Pennsylvania.
Not if it didn’t originally come with one, which I’m pretty sure it didn’t.
The vehicle must meet the emission requirements for the year of manufacturing. Since your vehicle didn’t orginally come with a catalytic converter, none needs to be installed.
Converters and unleaded fuel first appeared in 1975…In most states, these old cars are now exempt from emissions testing.
