This is a direct-fit front catalytic converter for the 2005-2009 Jeep Grand Cherokee (WK) with the PowerTech 4.7L V8 engine. It replaces the factory converter in the front Y-pipe position. It is meant to clear P0420 and P0430 emissions trouble codes and restore factory exhaust flow.
The housing is heavy-gauge stainless steel tubing, which resists road salt corrosion and thermal stress. Inside is a flow-through ceramic substrate with a washcoat that converts hydrocarbons, carbon monoxide and NOx.
Laser-cut mounting flanges and factory-placed O2 sensor bungs allow installation with the stock upstream downpipes. No custom cutting or welding is required. The unit is 46-state legal. It cannot be sold, shipped or operated on vehicles registered in California, New York, Colorado or Maine.
