Catalytic Converter Replacement Cost for Subaru Forester: What Owners Need to Know GuideMechanic.Com For many Subaru Forester owners, the combination of reliability, versatility, and rugged capability makes it a favorite choice for city driving and weekend adventures.
However, like all vehicles, Foresters are not immune to wear and tear — and one of the critical components that may eventually require attention is the catalytic converter.
If you’re experiencing performance issues, a check engine light, or trouble passing emissions inspections, you might be facing a catalytic converter problem.
In this guide, we’ll break down the catalytic converter replacement cost for Subaru Forester, factors influencing the price, signs of failure, and ways to save money without compromising quality.

What Does a Catalytic Converter Do?
The catalytic converter is a crucial part of your Forester’s exhaust system. Its primary role is to convert harmful exhaust gases, including:
- Carbon monoxide (CO)
- Hydrocarbons (HC)
- Nitrogen oxides (NOx)
into less harmful substances like carbon dioxide (CO₂), water vapor, and nitrogen. This chemical reaction is facilitated by precious metals inside the converter, such as platinum, palladium, and rhodium.
Without a properly functioning catalytic converter, your vehicle would release excessive pollutants, harming the environment — and you could fail to meet local emission standards.
Signs of a Failing Catalytic Converter in a Subaru Forester
Detecting a faulty catalytic converter early can save you money and protect your engine. Some common symptoms include:
- Check Engine Light On (common codes: P0420 or P0430)
- Reduced Engine Performance (sluggish acceleration)
- Rattling Noises under the vehicle (broken internal components)
- Increased Fuel Consumption
- Dark or Smelly Exhaust Smoke (rotten egg smell)
- Failed Emissions Test
If you notice any of these symptoms, it’s best to have your Forester inspected by a qualified mechanic as soon as possible.
How Much Does It Cost to Replace a Subaru Forester Catalytic Converter?
Catalytic converter replacement costs for the Subaru Forester vary based on several factors:
- Model year
- Engine size (2.5L, turbocharged, hybrid models, etc.)
- Number of catalytic converters (some Foresters have more than one)
- OEM vs. aftermarket parts
- Labor rates in your area
Cost Breakdown (Typical Estimates)
| Category | Cost Range (USD) |
|---|---|
| Aftermarket Catalytic Converter | $350 – $800 |
| OEM Catalytic Converter | $900 – $2,200 |
| Labor (2–4 hours) | $200 – $500 |
| Total Estimated Replacement Cost | $550 – $2,700 |
OEM vs. Aftermarket Catalytic Converters: Which Is Better?
When replacing your catalytic converter, you’ll need to decide between an OEM (Original Equipment Manufacturer) part and an aftermarket one.
OEM (Genuine Subaru Parts)
- Exact fit and quality
- Longer lifespan
- Maintains emissions compliance
- More expensive
Aftermarket
- Lower upfront cost
- Varying quality levels
- May not always meet strict emissions standards (especially in California, where CARB-compliant parts are required)
- Warranty may be shorter
If your Forester is relatively new or still under warranty, choosing OEM is usually best. For older models (say, pre-2014), a quality aftermarket converter can be a practical and budget-friendly option.
Subaru Forester Catalytic Converter Replacement Cost by Model Year
| Model Year | Estimated Total Cost (USD) |
|---|---|
| 2009–2013 | $600 – $1,200 |
| 2014–2018 | $750 – $1,500 |
| 2019–2023 | $1,200 – $2,500 |
Newer Foresters have more complex exhaust systems, often with multiple catalytic converters, raising both parts and labor costs.
Can You Drive a Subaru Forester With a Bad Catalytic Converter?
Technically, yes — but it’s not recommended.
Driving with a failing catalytic converter can lead to:
- Significant engine performance problems
- Reduced fuel efficiency
- Damage to oxygen sensors
- Overheating of the catalytic converter, which can cause further damage
Failed emissions inspections, leading to fines or inability to register your vehicle
In extreme cases, a completely clogged catalytic converter can cause your engine to stall or prevent it from starting altogether.
Is Catalytic Converter Theft a Risk for Subaru Forester Owners?
While hybrids (like the Toyota Prius) are the primary target for catalytic converter theft, some Subaru models, including certain Foresters, are also occasionally targeted. Thieves seek the precious metals inside, and SUVs like the Forester, which have higher ground clearance, are easier to access.
How to Protect Your Subaru Forester:
- Install a catalytic converter shield or cage
- Park in secure, well-lit areas
- Etch your vehicle’s VIN number onto the converter
- Use security cameras if parking at home
Will Warranty or Insurance Cover Catalytic Converter Replacement?
Manufacturer’s Warranty
Subaru typically provides an 8-year/80,000-mile federal emissions warranty for catalytic converters in the U.S. If your Forester is still under this coverage, your replacement may be free or significantly discounted.
Car Insurance
If your catalytic converter is stolen, and you have comprehensive insurance, the replacement is usually covered (minus your deductible). Damage from regular wear and tear, however, is not typically covered.
Tips for Saving Money on Catalytic Converter Replacement
Here are some ways to reduce the cost of catalytic converter replacement:
Compare quotes
Get at least three estimates from different repair shops.
Buy parts independently
Purchase a certified aftermarket catalytic converter online and pay a local mechanic just for installation.
Prevent further damage
Address engine misfires, bad oxygen sensors, and rich fuel mixtures quickly. These problems can destroy a new catalytic converter prematurely.
Check for Recalls or Technical Service Bulletins (TSBs)
Occasionally, manufacturers issue recalls for catalytic converters. Subaru has had recalls in the past related to emission systems, so it’s worth checking.
How Long Does It Take to Replace a Subaru Forester Catalytic Converter?
Most catalytic converter replacements for a Subaru Forester take between 2 to 4 hours, depending on the accessibility of the part and whether additional repairs (like replacing oxygen sensors) are needed.
If the bolts are rusted or the catalytic converter is integrated with the exhaust manifold, expect the job to lean toward the longer and more expensive side.
Final Thoughts
Replacing the catalytic converter on your Subaru Forester is a necessary but sometimes costly maintenance task. Depending on your model year, engine type, and location, you can expect to spend between $550 and $2,700 for parts and labor combined.
Recognizing the early warning signs, choosing the right type of replacement part, and working with a reputable mechanic can help you manage costs and get back on the road quickly — with your emissions system working perfectly.
Whether you’re driving a rugged 2010 Forester or a tech-packed 2023 model, keeping your catalytic converter in good condition is key to maintaining your vehicle’s performance, efficiency, and environmental responsibility.
