What It Is

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.
