What Does a Catalytic Converter Look Like? (Photo Guide)
Posted: January 2, 2026
A catalytic converter looks like a metal canister—often oval or cylindrical—found along your vehicle’s exhaust system. It typically has heat shields, welds on both ends, and may feel heavy due to the precious metals inside.
If you’re looking under your car and unsure what you’re seeing, this guide breaks it down with clear photos of OEM, aftermarket, foreign, and domestic converters. Plus, we’ll show you exactly where to look and how to take the best photos for a scrap quote.

Photos of OEM Converters
Original Equipment Manufacturer (OEM) catalytic converters are the ones that came with your vehicle from the factory. They tend to be heavier, better built, and more valuable than aftermarket ones. Here are examples from common brands:
- Toyota Converters – Often rectangular or barrel-shaped with part numbers stamped into the shell.
- Ford & GM Converters – Usually have a honeycomb shape and may come with dual units.
-
- Ford OEM Cat
-
- Toyota Cat
Foreign vs. Domestic Converters
- Foreign (Import) Converters: Tend to be smaller and often have more ceramic inside. Popular on brands like Toyota, Honda, and BMW.
- Domestic Converters: Common on vehicles like Ford, Chevy, and Dodge. Often larger and heavier.
Photos can help sellers quickly identify which category their fall into.
Aftermarket Examples
Aftermarket converters are replacements installed after the factory part is removed. These typically have less precious metal content, making them less valuable for scrap.
- Signs of aftermarket: No OEM part numbers, shiny/newer metal, less weight.
Note: We do not quote aftermarket cats.
(Include photos of aftermarket converters with labels.)
Where to Look on Your Vehicle
Most catalytic converters are located:
- Under the car along the exhaust system
- Near the engine or muffler
- Connected with bolts or welded in place
Use a flashlight and phone camera to safely inspect the undercarriage. Diagrams or arrows can help guide the search.

How to Identify It for Scrap
To help us quote your converter, here’s what to look for:
- Shape and size (Is it round, oval, or flat?)
- Welded or bolted? You can remove it either way
- Part numbers (stamped on the body)
- Any heat shields or additional units?
The more details we see, the more accurate your quote.
Tips for Photo Submission
