It's a common belief that all catalytic converters place a choke-hold on performance. Random Technology disproves that theory with their Super High Flow catalytic converters. Removal of a converter is not only an illegal modification but likely to decrease horsepower. Obviously gas mileage and horsepower vary, but by using a high efficiency catalytic converter, an engine will produce maximum power while remaining emissions legal. Stainless steel construction with monolith type ceramic/metallic bricks rather than pellets. Monolith type converters are more efficient since their honeycomb construction provides lots of small passages for exhaust gas to flow. Installation kits , sold separately, include necessary hardware. Please have Vehicle Year, Model & Engine size ready when ordering. more...
5 Year, 50,000 mile warranty.

Product Details

Random Technology catalytic converters actually have a higher flow capacity than many mufflers. As an example, a 3" diameter 9000 series SuperStainless converter flows 502 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.

Under Federal EPA regulation, replacement of original catalytic converters is allowed only if the original converter(s) is missing, or the vehicle has more than 50,000 miles or is at least five years old and the need for a replacement has been established and documented, or a local inspection program has determined the existing converter is in need of replacement.
