How many catalytic converters are on a Subaru Outback?
Most Subaru Outback models use two catalytic converters, arranged as a close-coupled catalytic converter near the engine and a second downstream in the exhaust path. This two-cat setup is typical for common engine options like the 2.5-liter four-cylinder and the 3.6-liter H6 across many model years, though exact configurations can vary by year, market, or aftermarket modifications.
Typical count and placement
This section explains the standard arrangement you’ll typically find on a Subaru Outback.
- Two catalytic converters are standard in most Outback configurations: a primary cat located near the engine and a secondary cat positioned further back along the exhaust stream.
- The dual-cat setup works with Subaru's dual-exhaust design and boxer engine layout to meet emission requirements while maintaining performance.
Two-catalyst setups are common, but always verify with your vehicle’s service data or VIN for your exact model year and engine.
Variations by model year and market
Engine choices, emission standards, and production year can influence the exact exhaust layout. While the two-cat design is typical, some early-generation Outbacks or market-specific variants may differ. Always consult the owner's manual or a Subaru service bulletin for your exact VIN.
Common steps to verify on your vehicle
To determine the exact number on a given Outback, you can inspect the underside or consult documentation. Use the steps below for a quick check.
- Park safely and locate the exhaust system under the vehicle; look for two distinct catalytic converter housings along the exhaust pipe—one near the engine and one downstream.
- Count the catalytic converters: typically you should see two in standard setups; some aftermarket or modification scenarios may add or remove units.
- Refer to the vehicle's VIN-based build sheet or Subaru service data to confirm the exact emissions equipment for your specific model/year.
In practice, two catalytic converters are the norm for most Subaru Outback models, but verifying with official documentation is the best way to be certain for your particular car.
Summary
Most Subaru Outback models employ two catalytic converters—one close to the engine and one further downstream—in a dual-exhaust configuration. This arrangement meets emission standards across the common 2.5L and 3.6L engines and a wide range of model years. However, exact configurations can vary by year, market, or aftermarket modifications, so always check your specific vehicle documentation or VIN for precise details.
