How much does it cost to replace a catalytic converter on a traverse?

For a Chevy Traverse, a catalytic converter replacement typically costs between about $200 and $1,000 per unit with aftermarket parts, or roughly $700 to $2,000 per unit with OEM parts, including labor. If both converters need replacement, expect about $1,400 to $4,000 in total.

What affects the price

The price you see reflects several factors, including the part choice, the number of converters, and local labor rates. Some Traverse models use two catalytic converters, and access varies by year and engine. Here's how costs break down:

• Parts: Aftermarket catalytic converters typically cost about $100–$600 per unit, while OEM (original equipment) units can range from roughly $600–$2,000 per unit.


• Labor: Labor time for replacing a catalytic converter is commonly 1–3 hours per unit, with shop rates around $80–$150 per hour, depending on the market.


• Vehicle specifics: Engine type (for example, a 3.6L V6), the number of converters (one or two), and whether oxygen sensors or other sensors must be replaced or re-torqued.


• Additional costs: Diagnostic fees, disposal fees, taxes, and potential extra charges for rusted bolts or related exhaust components.

In practice, the total you pay will reflect the exact vehicle year, engine, part choice, and local shop rates.

Typical price ranges by scenario

These examples illustrate common price brackets you might see when shopping for a Traverse catalytic converter replacement. Prices are ballpark figures and can vary by region and shop.

• One converter replaced with aftermarket parts: Total typically around $200–$950 (parts + labor).


• One converter replaced with OEM parts: Total typically around $700–$2,450 (parts + labor).


• Both converters replaced with aftermarket parts: Total typically around $360–$1,900 (parts + labor).


• Both converters replaced with OEM parts: Total typically around $1,360–$4,900 (parts + labor).

Note: These figures assume standard labor rates and do not include any state or local taxes, disposal fees, or diagnostic charges. Always obtain multiple quotes for an accurate comparison in your area.

DIY vs professional replacement

Replacing a catalytic converter is generally a job best handled by a professional mechanic. It involves cutting and welding exhaust pipes, handling heat and potentially damaged fasteners, and ensuring sensors are properly connected to avoid emission issues.

DIY considerations

If considering a DIY approach, be aware that improper installation can lead to exhaust leaks, sensor damage, or failed emissions tests. Tools such as a proper jack and stands, penetrating oil, oxygen sensor sockets, and welding equipment may be required. Always check local regulations and emissions requirements before attempting a DIY replacement.

Summary

Replacing a catalytic converter on a Chevy Traverse typically costs a few hundred to a few thousand dollars per unit, depending on whether aftermarket or OEM parts are used and on labor rates. If both converters are involved, the total can range from roughly $1,400 to $4,900 or more. To get an accurate quote, obtain multiple estimates from local shops and confirm whether parts are aftermarket or OEM, plus any diagnostic or disposal fees.

How to cheaply fix a catalytic converter without replacing it?

If the catalytic converter itself is solid, it can be repaired very cheaply. An exhaust shop can weld in metal tubing for almost nothing. If they can simply replace the broken connection with a piece of straight exhaust tubing and weld it directly to the catalyst, this can likely be done for under $100.

How much does it cost to replace a catalytic converter on a Chevy Traverse?

The average cost for a Chevrolet Traverse Catalytic Converter Replacement is between $3,405 and $3,515. Labor costs are estimated between $181 and $266 while parts are priced between $3,224 and $3,249.

Can I still drive with a bad catalytic converter?

You can technically drive with a bad catalytic converter, but it's not recommended, especially if it's clogged, as it can lead to engine damage, poor performance, and potential legal issues. If the converter is simply inefficient but not blocked, you may be able to drive for a while, but if it becomes clogged, it can cause severe issues like engine misfires or a total loss of power, as the exhaust cannot escape. A professional diagnosis is needed to determine the extent of the problem.

Risks of driving with a bad catalytic converter

• Engine damage: A clogged converter can cause extreme back pressure, which can damage engine components like crankshafts, rings, and bearings over time. 
• Poor performance: You may experience a significant loss of power, engine misfires, rough idling, and an inability to accelerate past a certain speed. 
• Legal issues: In many areas, it is illegal to drive with a faulty or missing catalytic converter, and you could be fined or fail an emissions test. 
• Increased emissions: A failing converter will not properly clean the exhaust, leading to increased pollution. 

What to do if you suspect a bad catalytic converter

• Avoid driving: If you suspect a clogged converter, it is best to avoid driving the car to prevent further damage. 
• Get a professional diagnosis: Have a mechanic diagnose the issue to determine if the converter is clogged or just inefficient. 
• Consider towing: If you have to move the vehicle, consider using a tow truck to take it to a repair shop.

Is it worth replacing a catalytic converter?

Yes, replacing a catalytic converter is often worth it to avoid legal penalties, significant engine damage, and poor performance. While the initial cost is high, driving without one is not recommended due to the risk of failing emissions tests, a loud engine, reduced fuel efficiency, and potential damage to other engine components. 
Reasons to replace your catalytic converter 
This video explains the reasons why replacing a catalytic converter is worth it: 49sStudent LessonYouTube · Sep 18, 2023

• Avoid legal and inspection issues: Many states require a working catalytic converter to pass emissions and smog tests for vehicle registration. Driving without one is illegal in most places. 
• Prevent engine damage: A malfunctioning or clogged converter can cause the engine to work harder, leading to sluggishness, misfires, and other issues. Continued driving can lead to more extensive and costly engine damage or failure. 
• Improve vehicle performance: A new converter will restore engine performance, improve acceleration, and can prevent other problems like stalling. 
• Increase fuel efficiency: A clogged converter can decrease your gas mileage, so replacement can improve your fuel economy. 
• Reduce harmful emissions: The primary function of a catalytic converter is to reduce harmful pollutants from your vehicle's exhaust, which is beneficial for the environment. 

When to consider replacement

• Signs of a problem: Look for symptoms like reduced engine power, a sulfur or rotten egg smell from the exhaust, poor acceleration, or a loud rattling noise from the exhaust system. The "check engine" light is often a sign of a failing catalytic converter, but it could also be triggered by other engine issues, so a proper diagnosis is important. 
• Cost vs. long-term cost: Even though replacement is expensive, the cost of ignoring the problem can lead to even more expensive engine repairs down the line. 
• Repair vs. replacement: If the catalytic converter is damaged, get an estimate for both repair and replacement. Often, replacement is the better option if the repair cost is similar to a new part.
