If you own a 2018 Dodge Charger V6, the factory exhaust may feel too quiet for the car’s muscular look. A well-matched cat-back exhaust can give your Charger a deeper, more confident sound while keeping the upgrade focused on daily driving, fitment, and long-term durability.
This updated guide focuses only on cat-back exhaust systems that fit the main buyer intent. Products with unclear 2018 fitment or the wrong category were removed, so you can compare the remaining BORLA options without sorting through mismatched parts.
Before ordering, always confirm your exact trim, drivetrain, bumper setup, and tip requirements on Amazon or with the manufacturer. Exhaust fitment can vary, and a quick check before checkout can prevent return hassles or extra shop labor.
Quick Verdict
Best Overall: Choose the BORLA 140686 Cat-Back Exhaust System if you want the most aggressive sound-focused option for a 2018 Dodge Charger V6.
Best Premium Alternative: Choose the BORLA 140685 Cat-Back Performance Exhaust System if you want BORLA construction quality and a refined performance sound, but make sure you verify the exact tip and valance requirements before ordering.

How We Chose the Best Exhaust Systems for Your Charger V6
We focused on exhaust systems that match the main reason you are here: improving the sound and character of a 2018 Dodge Charger V6 with a cat-back upgrade. Products with older model-year fitment, unclear compatibility, or a different purpose were removed from the final recommendations.
Sound profile was the next priority. Some Charger V6 owners want a deep, aggressive rumble, while others want a more polished performance tone that does not feel excessive during normal driving.
We also considered material quality, installation style, fitment clarity, buyer hesitation, and how easy each option is to compare. Since exact ratings, review totals, availability, and pricing can change, those details should be checked directly on Amazon before purchase.
Before You Buy: Fitment Checklist
- Confirm your car is a 2018 Dodge Charger V6, not a V8 trim.
- Check whether your Charger is RWD or AWD.
- Review the bumper, valance, and exhaust-tip notes before ordering.
- Compare Amazon’s fitment checker with the product description.
- Use a professional exhaust shop if you are not comfortable aligning a cat-back system.
BORLA 140686 Cat-Back Exhaust System

FAQ
What kind of sound can I expect from an aftermarket exhaust on my 2018 Dodge Charger V6?
You can expect a deeper and more aggressive sound than the factory exhaust. A V6 will not sound exactly like a HEMI V8, so the best goal is a cleaner, stronger V6 tone rather than a fake V8 sound.
Are these exhaust systems a direct fit for my 2018 Dodge Charger V6?
They are presented as vehicle-specific cat-back systems, but you should still confirm your exact model, trim, drivetrain, bumper, valance, and tip details before buying. Exhaust fitment can vary enough that a final compatibility check is worth doing.
Besides sound, what benefits can a cat-back exhaust provide?
A well-designed cat-back exhaust can improve exhaust flow and throttle feel, but you should not expect dramatic horsepower gains from an exhaust alone. The biggest reasons to upgrade are sound, material quality, appearance, and driving enjoyment.
Should I install a Charger V6 cat-back exhaust myself?
If you have exhaust tools, jack stands or lift access, and alignment experience, installation may be manageable. If not, a professional exhaust shop can help prevent leaks, rattles, hanger issues, and rear-tip alignment problems.

Wrapping Up

The best exhaust is not just the loudest one. It is the one that fits your car correctly and gives you the tone you actually want to live with.
If you want the boldest pick here, start with the BORLA 140686 Cat-Back Exhaust System. If you want a premium alternative and are comfortable checking the details carefully, compare it with the BORLA 140685 Cat-Back Performance Exhaust System.
