A direct-fit replacement assembly that combines the engine Y pipe with two catalytic converters in one unit. It is built for the 2002–2004 Jeep Grand Cherokee 4.7L V8, in both two- and four-wheel drive. It has four O2 sensor ports, a 36-inch overall length and two-bolt loose flanges at each end, so it bolts in place of the factory part. The main trade-off is legal: it is not legal for sale or registration in California, and it cannot ship to California or New York.

This is a new, direct-fit catalytic converter assembly made in the USA. It is an EPA-approved replacement for 2002-2004 Jeep Grand Cherokee models with the 4.7L V8 engine, in 2WD and 4WD. It is intended for Federal and California emission vehicles, but it is not legal for sale for vehicles licensed in California.
The assembly has dual converters with an engine Y pipe and four O2 ports. It is 36 inches long overall and has a 2-bolt loose flange at both ends. The body is made of alloy steel, mild steel and steel, and the substrate is ceramic and platinum. It is sealed, needs no drilling and is a direct fit.
Converters are designed to last the life of the vehicle. A converter that needs replacing points to an emissions or engine tuning problem, which should be corrected before installing this part. Converters that have turned blue from overheating are not covered under warranty.
