Selling your catalytic converter separately can pay more than leaving it on the vehicle, but there are legal restrictions and practical considerations.
Pros and cons of selling separately:
| Selling Separately | Leaving on Vehicle |
|---|---|
| Higher potential payout ($100 to $500+) | Simpler transaction |
| Requires removal (tools and time) | No extra work |
| Legal restrictions in many states | No legal concerns |
| Need to find a licensed buyer | Junk car buyer handles it |
| Vehicle offer drops significantly | Full vehicle value included |
Legal considerations:
- Many states require proof of ownership to sell a catalytic converter
- Some states only allow sales to licensed recyclers
- Selling without documentation may be illegal or raise theft concerns
- Penalties for illegal converter sales include fines and criminal charges
When selling separately makes sense:
- You have a high-value converter (hybrid, truck, luxury vehicle)
- You can prove ownership with title and ID
- Your junk car offer is very low
For most sellers, leaving the converter on the vehicle is easier. Buyers who purchase junk cars for cash include its value in the quote, handle removal, and take on the resale process.
