Replacing a catalytic converter on a Chrysler 300 typically costs between roughly $900 and $2,500, depending on engine type, how many converters need replacement, and whether you choose aftermarket or OEM parts. This range reflects parts plus labor and can vary by location and shop.
Chrysler 300 models vary by engine and exhaust configuration. The common V6 (3.6L) often has two catalytic converters—one on each bank—while V8 configurations can involve additional converters. The total bill rises with the number of converters replaced, the choice between aftermarket and OEM parts, and the labor rate at the repair shop. The following sections break down what drives the price and what you can expect in typical scenarios.
What drives the cost
Below are the main factors that influence the final price you’ll pay for catalytic converter replacement on a Chrysler 300.
- Engine type and number of catalytic converters required
- OEM versus aftermarket replacement parts
- Labor rates and the repair shop’s location
- Accessibility and complexity of the exhaust system
- Additional parts or services (gaskets, oxygen sensors, mounting hardware)
- State or local requirements, including emissions testing and potential fees
In practice, these factors determine whether you pay toward the lower end of the spectrum or the higher end, especially if multiple converters must be replaced or if OEM parts are specified by your vehicle’s warranty or local regulations.
Typical cost ranges for a Chrysler 300
The following price ranges reflect common scenarios for a Chrysler 300, based on current market prices for parts and typical labor rates. Figures are approximate and can vary by region and shop.
- Aftermarket parts, single converter: total around $400–$900
- Aftermarket parts, both converters: total around $800–$1,900
- OEM parts, single converter: total around $700–$1,400
- OEM parts, both converters: total around $1,400–$3,000
Prices can be higher if a converter theft is involved, if additional exhaust components must be replaced, or if a shop charges a diagnostic fee on top of the replacement. Conversely, you may find lower quotes at independent shops or during promotions, especially when aftermarket converters are approved by the vehicle manufacturer or by state regulations.
Getting an accurate quote
To ensure you’re paying a fair price, obtain written estimates from several reputable shops. Ask the shop to itemize parts and labor, confirm whether the price includes any required oxygen sensors or gaskets, and inquire about warranties on the new converter and labor. If you’re unsure whether aftermarket or OEM parts are right for your car, discuss the pros and cons with the technician and consider regional emissions requirements before proceeding.
It’s also wise to verify that the quote accounts for any necessary inspection or diagnostic work to confirm that the catalytic converter is indeed the failing component, and to check for related issues that could affect the emissions system, such as a faulty oxygen sensor or exhaust leaks.
Summary
For a Chrysler 300, replacing one catalytic converter with aftermarket parts typically runs a few hundred to about a thousand dollars, while replacing both can approach two thousand dollars or more. OEM parts tend to be pricier, with dual-converter replacements often pushing the total toward the higher end of the spectrum. The exact price depends on engine configuration, the number of converters affected, part choice, labor rates, and regional factors. Getting multiple quotes and asking for itemized estimates will help you understand the true cost for your specific vehicle.
