Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4451499. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This Direct-Fit Catalytic Converter is designed to fit the 1996-1997 Nissan Pathfinder 3.3L & 1997 INFINITI QX4 3.3L. MagnaFlow 4451499 interchanges with OE parts B08A0-0W000, B08A0-0W500. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

Hannah ★★★★★

Finally got my QX4 to pass the smog test after swapping in this converter. The direct-fit flanges lined up perfectly, so I didn’t need a shop to weld anything. Check engine light hasn’t come back on in the two weeks since the install.

Sebastian I. ★★★★★

Bolted right up to my '97 Pathfinder without any modifications needed, and the check engine light has stayed off for two weeks now. The mandrel-bent tubing gives it a clean, solid fit under the chassis.

Grace H. ★★★★★

The honeycomb substrate is visibly dense, and the welds look clean—no exhaust leaks after a week of driving. CARB sticker was included, which made passing smog a breeze. Glad I spent the extra on this one.
