It depends on the engine. The 2015 Charger uses two catalytic converters with the 3.6L V6, and four catalytic converters with the 5.7L or 6.4L Hemi V8 engines.
Understanding the question requires looking at the Charger’s different engine options for that year. The Charger line offered a 3.6L V6 for base and mid-range trims and larger V8 options for higher-performance variants. Emissions configurations and market requirements influence how many catalytic converters are installed on each engine. Below is a breakdown by engine type, followed by practical notes on what that means for maintenance and identification.
Engine-by-engine Catalytic Converter Count
The following breakdown reflects common factory configurations for the 2015 Charger by engine type. It notes the typical number of catalytic converters and their general arrangement. Individual vehicles may vary due to market, emission certifications, and aftermarket modifications.
- 3.6L Pentastar V6 (base/GT models): two catalytic converters total (one on each bank).
- 5.7L Hemi V8 (R/T and related trims) and 6.4L Hemi (SRT and related trims): four catalytic converters total (two per bank, typically arranged as upstream and downstream catalysts in each bank).
In summary, the V6 configuration usually carries two catalytic converters, while the V8 configurations (5.7L and 6.4L) typically use four catalytic converters across both banks. Actual configurations can vary slightly by emission region and specific exhaust package.
Regional and Maintenance Considerations
How to verify on your vehicle
To confirm the exact number on a specific 2015 Charger, inspect the exhaust layout from the headers toward the rear or consult the vehicle’s service manual or VIN-specific diagrams. Look for two catalytic converters on the V6 and four (two per bank) on the V8 models. Regional variations and aftermarket exhausts can alter the count.
Additionally, some markets require extra sensors (such as multiple oxygen sensors) and may influence the arrangement and placement of catalysts, but the total count typically follows the engine type as described above.
Summary
The 2015 Dodge Charger generally uses two catalytic converters with the 3.6L V6 and four catalytic converters with the 5.7L or 6.4L Hemi V8 engines. Always verify with the specific vehicle’s documentation or a VIN-based diagram, especially if the car has an aftermarket exhaust or was imported to a different emissions region.
