Your check engine light is on, and the repair estimate has a catalytic converter on it. Before you agree, you need to know which converter the shop means and why that particular part costs so much.
So catalytic converter replacement is $800 to $2,500 at Joey’s Auto Service in Nutley, New Jersey. The Catalytic Converter Shop in Massachusetts prices a 2003 to 2012 Corolla 1.8L at $650.
I will walk you through those shop prices, the approval your replacement needs and three owners’ repair amounts. The pages were checked October 24, 2026.
What the Shops Charge
The Catalytic Converter Shop in Massachusetts has a vehicle price menu. These are its own TCCS prices; I have left out its comparisons with unnamed dealers and mechanics.
These menus give you something useful to compare with a quote, but they cover different vehicles and businesses. Ask which converter position, part number and installation work the offer covers.
Joey’s exhaust service page gives two to four hours for converter replacement. That is the shop’s time guidance; it does not give a separate converter labor price to add to its replacement range.
Match the Part to Your Car and State
A converter that fits the pipe still needs the right emissions approval. This matters before you order a cheaper part online or ask a muffler shop to fit one.
In California, CARB’s aftermarket converter rules require an approved application. The lookup uses make, model, model year, engine size and the test group or engine family.
Ask the installer to show the matching approval and part number. If you live elsewhere, have it confirm the requirements for your registration state rather than choosing by pipe diameter alone.
The converter in the cover photo is a removed part. Its shape illustrates the component, but it is not one of the replacements priced in the shop menu.
Check the Emissions Warranty Before Paying
The EPA’s federal warranty explanation includes catalytic converters among the major emissions components covered for eight years or 80,000 miles, whichever comes first.
The coverage starts when the vehicle is sold to its first owner and also applies to used vehicles. Ask the dealer whether your failure qualifies before paying an independent shop to replace the part.
Joey’s also replaces stolen converters and can discuss theft prevention, such as a converter shield.
What Owners Paid or Were Quoted
These three US accounts are from CarComplaints. I kept the dates and the difference between a paid repair and a proposed repair, so you can see what each amount actually bought.
- A Nashville, Tennessee owner of a 2005 Pathfinder paid $1,200 for a converter change, in a post published March 1, 2015. The owner reported that the hesitation remained afterward.
- A Phoenix, Arizona owner of a 2005 Pathfinder received a $2,000 converter estimate, in a post published May 25, 2013. Other proposed repairs were priced separately.
- A Salt Lake City owner of a 2007 Prius described a proposed $2,000 converter replacement in a post published June 12, 2017. The proposed piston-ring work was a separate amount.
Those older amounts are useful repair stories, rather than current offers. The Nashville account is also a good reason to ask what testing connects the symptoms to the part being replaced.
Find Out Why the Converter Failed
Modern Day Muffler in Wadsworth, Ohio checks for an upstream misfire or oxygen-sensor fault before replacement. Its explanation warns that leaving the cause unresolved can damage the new converter.
Have the shop explain its test results and separate any engine repair from the converter work. My misfire repair guide covers that other part of the bill.
If the trouble is a leaking pipe or loose exhaust joint instead, my exhaust leak guide can help you compare that smaller repair with a converter replacement.
Ask About the Replacement Part’s Warranty
Modern Day Muffler advises asking what warranty covers the specific part before work starts. Parts it installs carry their manufacturer’s warranty, which varies by brand and part.
Then compare a second quote for that same job. A quote for one converter and a quote for an entire exhaust assembly are answering different questions, even if both begin with the same warning light.
