| 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 high flow catalytic converters.
Direct-fit, bolt-in SuperStainless converters are available for most vehicles. Click here for application charts that contain specific part numbers for direct fit converters (no welding reqired) Direct fit converters have all necessary flanges and oxygen sensors (if required) as the original equipment converters. Click here for dimensions of universal fit converters which are designed to be welded or clamped in place. 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. See the "test results" page for actual dyno test data.
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 no aftermarket catalytic converters are 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 many mufflers. As an example, a 3" diameter 7000 series SuperStainless converter flows 598 cfm. Most 3" diameter high performance mufflers flow less than 475 cfm at the same test pressure. Random Technology direct fit SuperStainless catalytic converters are available for most domestic and imported vehicles. Custom catalytic converters with inlets and outlets up to 4" in diameter are available.
