Dodge Charger (2015–2023) · Cat-back exhaust
Is a Cat-back exhaust Worth It on a Dodge Charger?
Short answer · Depends
A cat-back replaces the exhaust from after the catalytic converter(s) back to the tips. It changes sound and can slightly change flow; it does not remove cats. For the 2015–2023 Dodge Charger (LD facelift years; Hellcat/Scat Pack and V6 share the platform but not exhaust or brake parts), Alone, power gains are usually small. Sound and weight are the main reasons people buy one. Pairing with a tune and other supporting mods is where numbers move more. Typical cost: Typical $500–$1,800. Difficulty: Moderate (jack stands, penetrating oil). A true cat-back keeps the catalytic converters, so emissions testing is usually unaffected—but loud systems can still break local noise rules. This page is general guidance—I am not claiming a personal install on every Charger kit listed in search results.

Fitment notes for the Dodge Charger
LD facelift years; Hellcat/Scat Pack and V6 share the platform but not exhaust or brake parts. Confirm V6 vs 5.7 vs 6.4 vs Hellcat before ordering intake/exhaust. Always match chassis code / generation—tuner catalogs often list sibling cars that look similar but use different brackets, MAF housings, or hangers.
Install difficulty
Moderate (jack stands, penetrating oil). Plan about 2–4 hours. Penetrating oil and proper jack stands matter more than the catalog photos.
Emissions / legal caution
A true cat-back keeps the catalytic converters, so emissions testing is usually unaffected—but loud systems can still break local noise rules.

FAQ
Does a cat-back exhaust add horsepower to a Dodge Charger?
Usually little you can feel on a stock tune alone. Real gains tend to show up with a proper tune and supporting mods.
Is a cat-back exhaust hard to install on a Charger?
Moderate (jack stands, penetrating oil). Budget about 2–4 hours. If you are not set up for DIY work, get a quote from a shop that knows this chassis.
Will this void my warranty?
In the US a modification alone does not void an entire vehicle warranty, but a dealer can deny a claim for a failure they can show the mod caused. Keep stock parts.
Did you test this exact kit?
Not as a blanket claim for every Charger listing. This verdict is general, generation-aware guidance so you know what to verify before you buy.
