Use these metallic substrate converters to add cats to existing header systems or replace existing ceramic cats. These are just the cats themselves, cutting, weldding and additional pipe or clamps will be required in order to install. 3 inch inlet / outlet, 200 cell per inch for super high flow, 4″ diameter small stainless steel body fits well within the stock side sill. Our super high flow catalytic converters feature 200 cell per inch metallic substrates that withstand extreme temperatures and vibrations that would degrade ceramic catalysts! Far superior to OEM cats and reduce interior temperatures dramatically. The small bullet design allows the 4 inch diameter, stainlees steel case to fit in very tight applications while resisting corrosion. Fully welded/spun construction eliminates seams that can leak or open under stress. Sold in pairs but available singular. Note: Not certified for use in California. Will pass emissions OBD2 and general emissions test, but do not carry a California EO number for non-stock replacement.
