The MagnaFlow 447231 is a direct-fit, CARB-compliant catalytic converter for the passenger-side rear position on 1999–2003 Nissan Frontier and 2000–2004 Xterra models with the 3.3L V6. It uses mandrel-bent stainless steel tubing and a single laser-fusion weld to match the original equipment design, so it installs without cutting or welding. It is one of the few converters that is legal in California and other CARB-restricted states for these vehicles. Compared with universal converters, it costs more but avoids fabrication and smog-check risk.

This is a direct-fit catalytic converter for the Nissan Frontier 3.3L (1999-2003) and Nissan Xterra 3.3L (2000-2004). It is designed to meet or exceed California Air Resources Board requirements. It has had additional testing to comply with CARB guidelines, so it can be used legally in California and CARB-restricted states on the listed vehicles.
The converter is built from 16 gauge 409 stainless steel tubing, which resists corrosion. Mandrel-bent tubing keeps the original design and geometry for smooth exhaust flow. A single laser fusion weld replicates the OE design and reduces the chance of a leak. The compact, low-mass design allows greater thermal efficiency. The barbed exhaust hangers are OE-sized and made of 410 stainless steel to reduce noise and vibration.
The converter bolts in with the proper tools. No cutting or welding is required. The required gaskets and hardware come in the box.
