The typical answer is two catalytic converters in the exhaust system of most 2013 Honda Accord models, with the exact arrangement depending on the engine and whether the car is a hybrid.
Typical exhaust layout for the 2013 Accord
The following describes the common, non-hybrid configurations found on most 2013 Accords in the U.S. market. It covers where to expect catalytic converters and how they are arranged within the exhaust path.
- Close-coupled catalytic converter near the exhaust manifold: the first converter that heats up quickly to reduce emissions at start-up.
- Secondary catalytic converter located downstream, usually along the mid-pipe or rear section of the exhaust: provides additional emission reduction as exhaust gas flows to the tailpipe.
In most cases, this yields a total of two catalytic converters in the exhaust system. Some hybrid variants may integrate or replace portions of the exhaust with different components, but the basic two-cat layout remains common for the non-hybrid 2013 Accord.
Notes by model variant
To be sure of your exact car, check the undercarriage near the exhaust or consult the owner's manual or a VIN-specific parts diagram. If you replaced a catalytic converter or are diagnosing an emissions issue, knowing whether your model uses one or two cats helps target repairs.
When to verify with the VIN
Automakers sometimes change exhaust layouts within a generation, or there can be variant-specific equipment (California emissions, for instance). For precise confirmation, pull the VIN and inspect the exhaust or confirm with a dealership or service bulletin.
Summary
In short, a typical 2013 Honda Accord (non-hybrid) uses two catalytic converters—one close to the engine and one downstream. Always verify for your exact trim and VIN, as hybrid variants and regional specs can vary.
