Replacing a catalytic converter on a Toyota 4Runner typically costs about $900–$2,500 for a single converter, and roughly $1,500–$4,000 if the vehicle has two converters. The exact price depends on part choice (OEM vs aftermarket), labor rates in your area, and whether both converters or downstream sensors need replacing.
Understanding this topic involves knowing how many catalytic converters your 4Runner has, what kind of replacement part you choose, and how your local shop’s labor rates factor into the total. This article lays out the main cost drivers, typical price ranges, and practical tips to get accurate quotes.
Key cost factors
Below is a breakdown of the main elements that influence the total cost of replacing a catalytic converter on a 4Runner.
- Number of catalytic converters: Many 4Runners have two converters (a pre-cat and a main cat). Replacing one vs. both can dramatically change total cost.
- Part type: Direct-fit OEM-style replacements from Toyota or aftermarket direct-fit catalysts typically cost more than universal or high-flow alternatives, but may fit with fewer complications.
- Vehicle year and engine variant: The exact setup (location and number of converters) can vary by model year and engine code, affecting both parts and labor.
- Labor rates and location: Shop hourly rates vary by region; urban areas or dealership service departments generally charge more than independent exhaust shops.
- Sensors and ancillary components: Downstream O2 sensors, gaskets, clamps, and mounting hardware may need replacement, adding to both parts and labor.
- Emissions and inspection requirements: Some regions require inspections and may require OEM parts or specific aftermarket compliance, influencing the choice of parts.
These factors together determine the final price you’ll see on a quote and explain why two identical cars can have different repair bills at different shops.
Typical price ranges
The following ranges reflect common scenarios as of 2024–2025 and can vary by locale and service provider.
- Parts cost per converter:
- Aftermarket direct-fit catalytic converter: generally $150–$600.
- OEM Toyota catalytic converter: typically $500–$1,400.
Before listing labor estimates, it’s helpful to know that labor costs depend on how long the replacement takes, which is influenced by the number of converters and accessibility of the exhaust system.
- Labor (per converter): approximately 1.5–3.5 hours at $100–$180 per hour, yielding about $150–$630 per converter.
- Other fees: taxes, disposal fees, gaskets/clamps, and potential sensor replacements can add $20–$200 or more depending on the job.
In practice, these components can combine to form a typical total cost range. If your 4Runner has a single converter and you choose aftermarket parts with moderate labor, you might see roughly $350–$1,200. If you’re buying OEM parts or replacing two converters, totals commonly run higher, often in the $1,200–$4,000 range depending on the exact configuration and local rates.
Cost scenarios by configuration
Because 4Runners commonly use two catalytic converters, the following scenarios illustrate how totals can scale with part choice and number of converters.
- Single converter replacement (one cat): Parts $150–$1,400; labor $150–$630; total roughly $300–$2,000 depending on OEM vs aftermarket and sensor work.
- Dual converter replacement (two cats): Parts $300–$2,800; labor $300–$1,260; total roughly $600–$4,100, with OEM parts pushing toward the higher end.
- OEM vs aftermarket considerations: OEM parts push costs higher but may offer factoryWarranty and guaranteed fit; aftermarket parts can save money but vary in quality and warranty.
Note that theft-related replacements or cases requiring aftermarket sensors or reprogramming can push totals toward the upper end of these ranges.
Tips to save money and get accurate quotes
Before requesting bids, prepare to obtain realistic, apples-to-apples estimates that reflect your vehicle’s exact condition and configuration.
- Provide your vehicle VIN and engine code when requesting quotes to ensure the shop lists the correct parts for your 4Runner.
- Ask for an itemized quote that separates parts, labor, sensors, and disposal fees, so you can compare apples to apples.
- Request both OEM and reputable aftermarket options, plus a warranty outline for parts and labor.
- Inquire about the need for sensor replacement or recalibration and whether the job will affect emissions testing in your area.
- Shop around: obtain written estimates from at least three independent exhaust shops and, if appropriate, a Toyota dealership for comparison.
With careful quotes, you’ll be better prepared to balance cost, reliability, and long-term durability for your 4Runner.
Summary
Replacing a catalytic converter on a Toyota 4Runner is a variable job that typically ranges from about $900 to $2,500 for a single converter and $1,500 to $4,000 for two converters, depending on OEM vs aftermarket parts, labor rates, and sensor needs. Key cost drivers include the number of converters, the choice of parts, and regional labor costs. To minimize surprises, obtain itemized quotes from multiple shops, consider both OEM and aftermarket options, and verify any emissions implications or warranty coverage before proceeding. If you suspect theft or damage, address safety and insurance considerations early in the process.
