How many catalytic converters does a 2017 Subaru Outback have?
The typical 2017 Outback uses two catalytic converters, though the exact count can depend on the engine option. In factory configuration, Subaru generally equips this model with two catalytic converters in the exhaust system.
Engine options and catalytic converter layout
The 2017 Outback was offered with two engines: a 2.5-liter four-cylinder and a 3.6-liter flat-six. In both configurations, the exhaust system is arranged with two catalytic converters along the path from the engine to the tailpipe.
The following details reflect typical factory layouts for the 2017 model year:
- 2.5-liter flat-4 (FA25) engine: two catalytic converters.
- 3.6-liter flat-6 (H6) engine: two catalytic converters (one on each bank).
These two converters are complemented by oxygen sensors that monitor catalytic efficiency. Exact placement can vary by trim and exhaust routing, but the total number of catalysts is two in standard factory configurations.
How to verify the count on your vehicle
To confirm the number on a particular car, inspect underneath the vehicle or consult the factory service manual for your VIN. Look for two distinct catalytic units along the exhaust path, typically with sensors located before and after each converter.
Maintenance and replacement considerations
Catalytic converters are used to reduce emissions and can fail over time due to overheating, contamination, or damage. Replacement is sometimes necessary if a bank's cat fails, but many replacements involve both units if the issue affects the entire exhaust path. If you’re replacing parts, coordinate with a qualified technician to ensure proper diagnostics and a correct, compliant setup for your engine variant.
Summary
For a 2017 Subaru Outback, the typical factory configuration includes two catalytic converters, regardless of whether you have the 2.5L four-cylinder or the 3.6L six-cylinder engine. Confirm with the specific vehicle’s service manual or a dealer if you need to be certain about your VIN, but two catalysts is the standard count for that model year.
