I recently had to replace the catalytic converter on my Toyota Prius and realized that many people may not know where the catalytic converter is located on their Prius.
After doing some research, I found that the location of the catalytic converter on a Prius can vary depending on the model year.
For the first and second generations of Toyota Prius (2001-2009), the catalytic converter is usually located on the underside of the vehicle. However, some models may have the catalytic converter located under the hood. It’s important to note that these generations of Prius have an expensive two-part catalytic converter that forms part of their exhaust pipes.
On the other hand, third and fourth-generation Prius models (2010-present) have a single catalytic converter located underneath the vehicle near the exhaust pipe.
While the location may differ between generations, it’s essential to know where your catalytic converter is located to prevent theft and ensure proper maintenance of your vehicle.
Where is the catalytic converter located on a Prius?
As a car enthusiast, I know that the catalytic converter is an essential component of the exhaust system. It helps to reduce harmful emissions from the engine before they are released into the atmosphere.
If you own a Toyota Prius, you might be wondering where the catalytic converter is located. In this section, I will provide you with some useful information that will help you find the catalytic converter on your Prius.
Locating the catalytic converter
The exact location of the catalytic converter on a Toyota Prius will depend on the model year and engine size. However, it is generally located somewhere between the tailpipe and the intake manifolds.
Toyota Prius hybrids have only one catalytic converter, either on the underside of the vehicle or under the hood.
The first and second generations of Toyota Prius (2001-2009) feature an expensive two-part catalytic converter that forms part of their exhaust pipes. It resembles a long cylinder with several chambers.
If you are having trouble locating the catalytic converter on your Prius, you can consult the owner’s manual for your vehicle.
The manual should have a diagram or a description of the exhaust system, which will help you identify the location of the catalytic converter.

As a Prius owner, it’s important to take measures to prevent catalytic converter theft. Here are a few tips:
- Park in a well-lit area: Thieves are less likely to target a car that is parked in a well-lit area. If possible, park your Prius in a garage or a well-lit parking lot.
- Install a catalytic converter shield: A catalytic converter shield is a metal plate that covers the catalytic converter, making it harder for thieves to access it. These shields can be purchased online or at your local auto parts store.
- Engrave your VIN number: Engraving your VIN number on your catalytic converter can make it easier to track down if it is stolen. Thieves are less likely to steal a catalytic converter that has been engraved.
