FixChevrolet Silverado 1500 — Catalytic Converter Replacement Cost
What owners actually paid
The shaded middle is where half of all these repairs landed: $360 – $873. A quote inside that band is normal. Cheaper or pricier isn't automatically wrong — but it's worth asking why.
What this repair is
The converter scrubs the exhaust, and a P0420 'efficiency below threshold' code is its signature complaint. The honest caution: a converter often dies from an upstream cause — misfires or oil burning poison it — so a good shop confirms the engine is healthy before hanging an expensive new cat. Precious-metal content is why the part alone dominates this price.
Is your quote fair?
If your quote lands between $360 and $873, it's inside the range where half of all real Chevrolet Silverado 1500 repairs of this kind land — and the typical job takes about 2 hours of labor. Quotes well below aren't automatically good news (economy parts, or related work skipped) and quotes above aren't automatically gouging (trim variants, premium parts, seized hardware) — but both ends deserve questions.
