Is this converter legal in California?

No. It is not CARB certified, so it is legal only in states that follow federal EPA rules. California and the states that adopted CARB standards require an approved converter with an executive order number.

Will it bolt up without welding?

Yes, on the vehicle it is built for. The flange inlet and pipe-connection outlet match the factory layout, so it installs with the original hardware and gaskets. It is not a universal part, so check the part number against your year, make, model and engine.

Does it have oxygen sensor ports?

Yes, two: one before and one after the converter. That matches vehicles that monitor catalyst efficiency with a downstream sensor.

What does HM Grade mean?

HM Grade is MagnaFlow's standard replacement line, built with a ceramic substrate and stainless steel body. It is aimed at stock or near-stock engines, not heavily modified ones.

Why is there no air tube?

The unit is built for engines that do not use an air injection tube. If your original converter has an air tube, this part is not the right fit.
