The vehicle uses two catalytic converters total—one on each bank of the engine.
In 2014, the Chrysler 300 was offered with either a 3.6-liter Pentastar V6 or a 5.7-liter Hemi V8. In both configurations, the exhaust system is designed with two catalytic converters—one per bank—to meet emissions standards, yielding a total of two converters. These units are typically located near the exhaust manifolds on each side of the engine.
Engine options and catalytic converter layout
The 2014 Chrysler 300 could be equipped with two different engines. Regardless of the powertrain, the car uses a dual-catalyst setup that results in two converters in total—one on each bank of the V engine.
3.6L Pentastar V6
The standard engine in most trims, the 3.6L V6, employs two catalytic converters—again, one on each bank of the engine—to meet federal emissions requirements.
5.7L Hemi V8
The optional 5.7L V8 also uses a two-cat arrangement, with a catalytic converter on each bank, aligning with emissions standards for that engine as well.
Why the two-converter setup matters
Understanding the two-converter layout helps with diagnostics, maintenance, and replacement decisions. If a fault arises, it can trigger bank-specific codes (such as P0420 or P0430) and affect performance or fuel economy. Aftermarket exhaust modifications can sometimes alter the number or placement of converters, so owners should verify the setup for their exact vehicle and VIN.
What to do if you suspect a problem
Common symptoms of a failing catalytic converter include reduced acceleration, poor overall performance, a rattling sound from under the vehicle, a noticeable sulfur or rotten-egg odor, or a Check Engine light. If you notice these signs, have a mechanic diagnose the vehicle with an OBD-II scan and, if needed, perform a catalytic converter inspection or replacement. Always confirm the exact configuration for your specific car, as trims or aftermarket changes can alter the setup.
Bottom line
For the 2014 Chrysler 300, anticipate two catalytic converters in the exhaust system—one on each bank of the engine—for both the 3.6L V6 and the 5.7L V8 configurations. If you’re unsure about your VIN or trim, consult a dealer or a qualified mechanic to confirm the exact number and placement of converters.
Summary
The 2014 Chrysler 300 generally uses two catalytic converters—one per bank—regardless of whether it has the 3.6L V6 or the 5.7L V8. This two-cat layout is standard for meeting emissions requirements on this model year, and owners should verify the configuration if planning maintenance or replacement.
