Random Technology SuperStainless 49 State Catalytic Converter for 00-06 Jeep Wrangler with 4.0L I-6 Engine

Whether you are rock climbing, bogging through mud or blasting through the back country, the catalytic converter on your Wrangler takes a lot of pounding. If you take your Wrangler to extremes, a standard converter's ceramic core can crack, causing it to fail. To eliminate that problem, Random Technology has introduced a new SuperStainless converter featuring a metal matrix core. In addition to eliminating the possibility of cracking, the metal matrix core also offers the highest flow capacity available. Not for use in California Emissions Vehicles.
