Is a Muffler Required to Pass a Vehicle Inspection if You Still Have a Catalytic Converter on the Exhaust System?

Whether or not a muffler is required to pass a vehicle inspection depends on the specific regulations in your state or locality. However, in most cases, the answer is no. A muffler is not required if you still have a catalytic converter on the exhaust system.

The purpose of a muffler is to reduce exhaust noise. The catalytic converter, on the other hand, is responsible for reducing harmful emissions. So, as long as your catalytic converter is working properly, you should be able to pass the inspection without a muffler.

Here are some additional points to consider:

• Some states may require a muffler for all vehicles, regardless of whether they have a catalytic converter.
• If your muffler is damaged or missing, you may fail the inspection.
• In some cases, you may be able to get a waiver from the inspection requirement if you can demonstrate that your vehicle is not causing excessive noise.
