How much does it cost to replace a catalytic converter on a Chevy Silverado?
The typical total to replace a catalytic converter on a Chevy Silverado ranges roughly from 800 to 2,500, depending on whether you need one converter or two, the engine and model year, and whether you choose aftermarket or OEM parts.
Costs can vary widely by region, shop, and whether your Silverado has a two-cat exhaust layout. Labor rates, vehicle configuration, and the need to replace sensors or other exhaust components can all push the bill higher. The following sections break down the main factors and typical price ranges to help you plan.
Cost determinants
Several factors determine the final bill for catalytic converter replacement on a Silverado. The list below explains the key price drivers.
- Number of catalytic converters: Some Silverado engines use one converter, while others (especially V8 setups with dual exhaust) may require replacing two. Replacing two almost always doubles parts and often labor costs.
- Parts choice: Direct-fit aftermarket converters are typically cheaper than OEM (GM) parts. OEM parts are more expensive but can come with longer warranties and a guaranteed fit.
- Vehicle model year and engine: The exact exhaust layout and sensor placement vary by year and engine (for example, 5.3L or 6.2L V8), which can affect both the complexity and price of the replacement.
- Labor rate and shop location: Dealerships and shops in urban or high-cost areas usually bill more per hour than independent shops in rural areas.
- Additional components: Replacing oxygen sensors, gaskets, clamps, or stainless steel exhaust hardware can add to the cost, especially if sensors are failing or require relocation.
- Emissions requirements: In states with strict emissions rules, there may be fewer affordable aftermarket options or additional certification requirements, which can raise price.
In short, your exact price will depend on how many converters you need, the part type you choose, and where you go for the repair.
Typical replacement cost ranges
Below are ballpark price ranges you might expect, depending on whether you replace one or two converters and whether you use aftermarket or OEM parts. These figures can vary by region and specific vehicle configuration.
- Single catalytic converter replacement (one unit): Aftermarket parts typically $150–$500; labor $150–$350; total $300–$850. OEM parts typically $500–$1,500; labor $150–$350; total $650–$1,850.
- Two catalytic converters replacement (common on many Silverado V8s): Aftermarket parts typically $300–$1,000; labor $300–$700; total $600–$1,700. OEM parts typically $1,000–$2,500; labor $300–$700; total $1,300–$3,200.
Note: If only one converter is failing and the other is still good, you may be able to replace just the needed unit, potentially reducing cost. Always obtain written estimates that break out parts and labor, and ask about any included warranties.
Summary
Replacing a catalytic converter on a Chevy Silverado is a repair that hinges on how many converters you need, the parts you choose, and local labor rates. Expect a broad range—from roughly $800 to $2,500 for most common configurations—though OEM parts and dual-converter jobs can push the total higher. Shop around for quotes, confirm whether parts are CARB-compliant where required, and verify any included warranties to ensure you’re getting value as well as a proper fix.
