The Chrysler 300 typically uses two catalytic converters—one for each bank of the engine. The exact count depends on the model year, engine choice, and emission package, so verifying for a specific car is advised.
What determines the number?
From year to year Chrysler offered several engines in the 300 lineup, including V6 and V8 options. Differences in exhaust routing, regional emission rules, and performance packages can influence how many catalytic converters are installed and where they sit along the exhaust. In practice, most factory setups feature one catalyst per bank, with any additional catalysts occurring only in particular configurations or markets.
To understand for a given vehicle, it helps to know the engine type and the emission package, which you can confirm via the vehicle's VIN or the original window sticker.
Below is a quick guide to the engines used in the Chrysler 300 over the years and the typical catalytic converter setup for each configuration.
- 3.5L V6 (early generations): typically two catalytic converters (one per bank).
- 3.6L Pentastar V6 (2011–present): typically two catalytic converters.
- 5.7L Hemi V8 (various years): typically two catalytic converters (one per bank).
- 6.4L Hemi (SRT/performance models): typically two catalytic converters (one per bank).
In all common factory configurations, count is two catalytic converters. If you have a specific model year or market version, verify with the factory documentation or by inspecting the exhaust system on your car.
How to verify on your Chrysler 300
To confirm the exact number on your vehicle, perform a quick physical check and cross-check with documentation:
- Safely raise the car and locate the exhaust system beneath the floor of the vehicle.
- Look for catalytic converter canisters along the exhaust path between the exhaust manifolds and the rear mufflers. You should typically see one canister on each side of the vehicle's underbody, corresponding to the two banks of the engine.
- Count the canisters; note any additional catalytic components near the engine or downstream in the exhaust route, which could indicate a different emissions configuration for your market.
- Cross-check the engine code and spec sheet (VIN decode or dealer invoice) to confirm the exact setup for your car.
Bottom line: while two catalytic converters are the norm, the precise count for any Chrysler 300 depends on the engine, year, and market. Verifying on the actual vehicle ensures accuracy.
Summary
The typical Chrysler 300 configuration uses two catalytic converters, one for each bank of the engine. The exact number can vary by engine and emissions package, so check the VIN, window sticker, or service diagrams for your specific car. A quick physical check beneath the vehicle can also confirm the count.
