The short answer
Catalytic converter replacement in Texas typically costs $900–$2,500 installed, depending on whether you choose an aftermarket EPA-compliant unit or an OEM part. Hybrids and trucks cost the most.
Theft prevention
Park in a garage or well-lit area, install a cage or shield, and etch your VIN on the converter. Texas law now requires sellers of used converters to provide documentation.
Signs of failure
Rattling under the car, rotten-egg smell, sluggish acceleration and a P0420 code.
