On a 2017 Hyundai Accent, catalytic converter replacement typically costs between $500 and $2,000 if you use aftermarket parts, or $1,000 to $2,500 if you opt for OEM dealer parts, with labor included. Final prices depend on the part you choose, local labor rates, and whether any related components must be replaced during the repair.
What affects the cost
Several factors influence the final bill. The most important are the type of catalytic converter you choose, how many converters the car actually needs, regional labor rates, and any related components that must be replaced at the same time.
Part options
Prices vary widely between aftermarket and OEM parts, and some Accent models may have a single converter while others could require additional catalytic components. The position of the cat, the engine type, and the availability of CARB-compliant parts in certain states also play a role.
- OEM/dealer catalytic converter: typically higher upfront part cost but may include a fuller warranty and guaranteed fit.
- Aftermarket direct-fit catalytic converter: usually cheaper than OEM and designed to bolt in with minimal modification.
- Universal or weld-in catalytic converter: often the least expensive part but requires cutting/welding and potential exhaust system modifications.
- Other related components: gaskets, clamps, heat shields, and downstream O2 sensors may be replaced at the same time, adding to the bill.
In short, the choice between OEM and aftermarket parts, plus whether welding or additional components are needed, largely drives the total price.
Pricing ranges by option
Below are typical ranges you might see in the United States as of 2024–2026. Prices can vary by region, shop, and vehicle specifics.
Direct aftermarket or OEM replacement ranges
These ranges assume a straightforward replacement on a 2017 Accent with a single catalytic converter and standard sensors.
- Aftermarket direct-fit catalytic converter: part roughly $150–$600; labor around $100–$350; total often $250–$900.
- OEM/dealer catalytic converter: part roughly $500–$1,400; labor around $150–$400; total often $650–$1,800.
For customers in regions with stricter emissions rules (such as CARB-compliant requirements in California), OEM or CARB-compliant aftermarket parts may be required, which can push the price higher.
Universal or weld-in options
If a universal or weld-in cat is chosen, parts tend to be cheaper upfront but require more labor and fabrication.
- Universal/weld-in catalytic converter: part roughly $100–$300; labor around $250–$700; total often $350–$1,000.
Note that welding and exhaust modifications can add time and risk, and not all shops recommend universal converters for street-driven cars due to fit and efficiency concerns.
What to expect at the shop
Most shops will start with a diagnostic to confirm the catalytic converter is the fault, often checking exhaust backpressure and sensor readings. The repair usually takes about 1–3 hours, depending on access and whether other components (like oxygen sensors or gaskets) are replaced concurrently. In CARB states, ensure any replacement part is CARB-compliant if required. Some shops may offer warranties on parts and workmanship, which can influence the overall value of the quote.
Summary
Replacing a catalytic converter on a 2017 Hyundai Accent typically costs between $500 and $2,000 with aftermarket parts, or $1,000 to $2,500 with OEM parts, including labor. The final price depends on part type, regional labor rates, and whether additional components must be replaced. To get the best value, compare multiple quotes, consider aftermarket direct-fit parts for savings, and ensure compliance with local emissions requirements. Planning ahead and understanding the options can help you navigate a repair that keeps your Accent on the road and compliant.
