⚠️ Critical Pre-Purchase Notice
-
Fitment Verification Reminder
Double-match your original catalytic converter’s OEM number and vehicle structure against our listing photos and compatibility chart before checkout. Mismatch caused by skipping comparison will result in avoidable returns.
-
Professional Installation Recommended
Exhaust system disassembly and sealing require specialized tools and experience. We advise certified auto shop installation for proper sealing and emission compliance.
-
Important Emission State Restriction
This converter meets Federal EPA standards ONLY. It is NOT CARB compliant and cannot be legally installed or registered in these states:
California, New York, Colorado, Maine
If your vehicle meets federal EPA specs but is registered outside the restricted states, this unit works perfectly for your car.

📚 How A Catalytic Converter Works
The catalytic converter is the core emissions control component on your vehicle’s exhaust system. It performs oxidation and reduction chemical reactions to neutralize toxic exhaust fumes:
-
Converts carbon monoxide (CO) into harmless carbon dioxide (CO₂)
-
Breaks down unburned hydrocarbons (HC) into water vapor and CO₂
-
Reduces harmful nitrogen oxides (NOₓ) into nitrogen and oxygen
When high-temperature exhaust flows through the ceramic substrate inside, precious metal catalysts accelerate these purification reactions to cut down air pollution and pass state emissions testing.
✨ Core Product Advantages

🔧 Step-by-Step Installation Guide
-
Raise the vehicle fully on a lift to expose the undercarriage exhaust system
-
Unbolt and remove your factory old catalytic converter along with connected exhaust piping
-
Mount this new direct-fit catalytic converter, coat all mounting bolt threads with anti-seize lubricant to prevent seizing

-
Let the vehicle run and scan for check engine / emissions fault codes to confirm leak-free operation
❓ Frequently Asked Questions
Q: Can I just replace the internal ceramic carrier instead of the whole assembly?
A: It is extremely difficult and unreliable to swap only the substrate. Full one-piece converter replacement is the recommended factory repair method to avoid exhaust leaks and failed emissions tests.
Q: How do I confirm my new catalytic converter functions correctly after installation?
A: Run the vehicle for 10–15 minutes to reach normal operating temperature. Use an OBD scanner to check for persistent exhaust/emission trouble codes. Monitor for recurring check engine lights during regular driving to confirm full functionality.
