Will this fit my car?

Only if your vehicle is on MagnaFlow's application list for part 52642. Check the year, engine and emissions standard before ordering, since one number covers a narrow set of cars.

Is it legal in California?

Only if this part number carries a CARB exemption for your vehicle. Federal converters are not legal for California-emissions cars, so verify the exemption before buying.

Does it need welding?

No. It is a direct-fit unit that replaces the factory converter with the stock flanges and hangers, so it usually bolts on with hand tools.

Does it include O2 sensor ports?

Yes. It has both pre-cat and post-cat sensor ports, and it has no air tube.

What is the pipe size?

The inlet and outlet are both 2.5 inches, matching the factory piping on the listed vehicles.

Will it fix a check-engine light?

If the light comes from a failed converter, a correct-fit replacement usually clears it. Have the codes read first, since O2 sensors and other faults can trigger the same light.

Our take on the Magnaflow Direct-Fit Federal Catalytic Converter 52642

The MagnaFlow 52642 is a direct-fit, stainless-steel catalytic converter with 2.5-inch inlet and outlet and pre- and post-cat O2 sensor ports. It bolts in place of the factory unit with little or no fabrication, which is its main advantage over universal converters that need welding and custom hangers. MagnaFlow builds it in the US with a ceramic substrate sized to the vehicle's emissions spec. Owners pick it for a factory-style fit and smog compliance; the trade-offs are cost and the fact that a single part number only fits specific vehicles.
