I know of this:

"As of January 1, 1988, all persons engaged in the business of automotive service and repair, as well as other parties named in section 203(a)(3) of the Clean Air Act*, are prohibited from installing or selling aftermarket catalytic converters which have not met the criteria of EPA's interim enforcement policy entitled 'Sale and Use of Aftermarket Catalytic Converters'* (published on August 5, 1986). The installation of non-complying converters by a named party will be considered a violation of section 203(a)(3) of the Clean Air Act, and the violator may be subject to a civil penalty of up to $25,000 for each improper installation."

But this doesn't get at what you were saying, so maybe there is something else.
