2013 Chevrolet Impala Catalytic Converters

Genuine GM catalytic converters for the 2013 Chevrolet Impala, at wholesale prices. Converters are emissions parts, and the substrate loading has to match what the ECM expects from the downstream oxygen sensor. W-body through 2013 and the Epsilon II from 2014 to 2020.

What sends people here

A P0420 code, rattling from underneath, or a failed emissions test. On a full-size car, trim level changes brake sizing, suspension and cooling parts within one model year.

Buying OEM, briefly

• GM stands behind it. The catalytic converters warranty comes from the manufacturer, not from us.
• Priced below the dealer. Catalytic Converters at up to 40 percent off list, with no membership.
• Factory sourced. These catalytic converters are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical catalytic converters numbers for you.
• Ships from Dallas. Catalytic Converters ordered by 3pm Central go out the same business day.

Before you order

Original tooling means original fit, which matters most on anything that has to align with a neighboring part. Our VIN lookup is more accurate than any public catalog. Use it before you check out. In stock orders placed by 3pm Central ship the same business day from our Dallas warehouse.
