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 Super High Flow catalytic converters.
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. Universal fit converters have the same flow characteristics as direct fit models with the same inlet and outlet diameter.
Independent testing by engine builders, racers, and automotive magazines has repeatedly proven the superiority of the Random Technology SuperStainless design.
This design, which meets Federal EPA and California ARB requirements, enables virtually any vehicle with a properly tuned engine to meet emissions standards with little, if any power loss (compared to an exhaust with no catalytic converter). Please note that it is illegal to remove a properly functioning catalytic converter and that aftermarket catalytic converters are not legal for installation in California on OBD II vehicles (some 1994 & 1995, and all 1996 and later vehicles).
In fact, Random Technology catalytic converters actually have a higher flow capacity than most mufflers. As an example, a 3" diameter Super High Flow converter flows 501cfm. Most 3" diameter high performance mufflers flow less than 475 cfm at the same test pressure. Random Technology direct fit Super High Flow catalytic converters are now available for most domestic and imported vehicles. Custom catalytic converters with inlets and outlet up to 4" in diameter are available.
