The catalytic converter cleans up harmful emissions before they leave the tailpipe. It contains precious metals like platinum and palladium, which is why it's expensive and frequently stolen.
Why It Matters
You cannot legally drive without a working cat in most states, and you'll fail emissions testing.
How to Save Money on Catalytic Converter Replacement
After-market direct-fit cats are 50 to 70 percent cheaper than OEM and work fine on older cars
Some states require CARB-compliant cats, check before buying a generic one
Anti-theft shields cost $150 to $300 installed, much cheaper than a replacement cat
