About Random Technology For years, it has been a common belief that all catalytic converters place a choke-hold on performance. In 1993, Random Technology disproved that theory with the introduction of SuperStainless free flow catalytic converters. In fact, Random Technology catalytic converters have been tested to be just as free-flowing as some mufflers!
Random Technology's direct-fit, bolt-in SuperStainless converters are available for most vehicles. Direct fit converters have all necessary flanges and oxygen sensors (if required) as the original equipment converters.
