Back when the 1973-1982 C3 Corvettes were rolling out of the factory and into the hands of eager owners, many do-it-yourself weekend warriors went straight to work removing the factory installed emission system because it robbed horsepower. We didn’t think we’d ever really need it, so we just threw the whole smog system on the junk pile.

Boy, were we wrong!

Today,  C3 show cars are REQUIRED to have the smog system if they were originally equipped that way. In addition, an intact system is needed to get the car registered or to renew license plates in some cities and states. Come to find out, an operating smog system is very important afterall!

But as owners decided to undertake this re-installation project, they found that most smog systems were hard to locate and very expensive.
