The Dodge Charger’s 3.6L Pentastar V6 comes from the factory with an almost silent exhaust, so a cat-back swap makes a much bigger audible difference here than it would on the V8 models. Fitment splits by generation — 2011-2014 LX-body Chargers and 2015-2023 LD-body Chargers use different part numbers even within the same brand, so match your model year carefully. All ten below are confirmed current listings for the 3.6L V6.

The picks, in detail
Borla S-Type Cat-Back Exhaust (140685)
Borla’s balanced daily-driver tune for the 2015-2023 V6 Charger (and 2015-2021 Chrysler 300 V6), aimed at adding tone without the drone that plagues cheaper systems on long highway drives.
- T-304 stainless steel construction
- Reuses factory bezel/valance (tips not included)
- Millon Mile Warranty
- Most road-trip-friendly tone of the picks here
- Borla’s stainless construction resists rust long-term
- One of the priciest options in this list
Borla ATAK Cat-Back Exhaust (140686)
Borla’s aggressive tune for the same 2015-2023 V6 Charger fitment as the S-Type, described by Borla as the loudest street-legal exhaust in their catalog for this platform.
- T-304 stainless steel construction
- Aggressive ATAK tuning
- Reuses factory bezel/valance
- Loudest legal Borla option for the V6 Charger
- Same durable stainless construction as the S-Type
- Loud enough that some owners find it fatiguing on long commutes
MagnaFlow Street Series Cat-Back Exhaust (15492, 2011-2014)
MagnaFlow’s Street Series system for the earlier LX-body V6 Charger, with dual split-rear-exit styling and straight-through mufflers for a moderate, non-drony tone.
- Mandrel-bent 409 stainless tubing
- Dual split rear exit
- Straight-through mufflers
- Fitment specific to the 2011-2014 body style, not a universal kit
- MagnaFlow’s straight-through mufflers minimize drone
- Doesn’t fit the redesigned 2015+ Charger body
MagnaFlow Street Series Cat-Back Exhaust (19522, 2019-2023)
The current-generation version of MagnaFlow’s Street Series for the redesigned LD-body Charger, with polished dual-exit tips and the same straight-through muffler design.
- Mandrel-bent 2.5-inch stainless tubing
- 4 straight-through mufflers
- Polished 4.5-inch dual exit tips
- Correct fitment for the current Charger body style
- Polished tips look factory-plus rather than aftermarket-loud
- Similar price to the more premium Borla options
MBRP Cat-Back Dual Rear Exit Exhaust
MBRP’s cat-back for the 2015-2023 V6 Charger, sold in aluminized or carbon-fiber-tip stainless finishes, positioned as the value option among the name-brand systems here.
- Dual rear exit
- Aluminized or stainless steel options
- T304 stainless tips on premium version
- Meaningfully cheaper than the Borla and MagnaFlow options
- Still a recognized performance-exhaust brand
- Aluminized base version won’t hold up as well long-term as the stainless competitors
Corsa Sport Cat-Back Exhaust (21064)
Corsa’s Sport-level tune for the 2015-2022 3.6L V6 Charger and 300, reusing the stock exhaust bezels and built with Corsa’s RSC (Reflective Sound Cancellation) valving to cut interior drone.
- 2.5-inch dual rear exit
- Reuses stock exhaust bezels
- RSC drone-cancelling technology
- RSC tech specifically targets highway drone, a common complaint on V6 cat-backs
- Limited Lifetime Warranty
- The most expensive system in this list
Flowmaster American Thunder Cat-Back Exhaust (817741)
Flowmaster’s American Thunder system for the 2015-2023 SE/SXT V6 Charger, pairing a Scavenger X-pipe with Super 44 mufflers and tuned resonators for Flowmaster’s signature deeper tone.
- Scavenger X-pipe
- Super 44 performance mufflers
- Specially-tuned resonators
- Flowmaster’s deep, muscle-car-adjacent tone stands out from the more refined imports on this list
- 304 stainless construction
- Flowmaster’s tone runs deeper/louder than the Borla S-Type if you want a subtler upgrade
Solo Performance Mach Cat-Back Exhaust
A specialist Charger/300 exhaust brand selling year-specific systems for the V6 platform — the Mach SXT LM for 2011-2014 and the Super Track Pack tune for 2015-2019 — both built around Solo’s own cyclone-style muffler.
- Year-specific tuning (2011-2014 vs. 2015-2019)
- Solo’s cyclone-style muffler design
- Stainless steel construction
- Brand builds nothing but Mopar-platform exhaust, with deep model-year-specific fitment knowledge
- Distinct tone from the more common Borla/MagnaFlow/Flowmaster options
- Among the pricier systems in this list
Pypes Street-Pro Cat-Back Exhaust (SMC26S)
Pypes’ X-pipe-equipped stainless cat-back for the 2011-2014 V6 Charger, using their own Street Pro mufflers — a mid-price option that undercuts the Borla and MagnaFlow systems by several hundred dollars.
- 2.5-inch mandrel-bent stainless tubing
- Pypes X-pipe
- Street Pro mufflers
- Meaningfully cheaper than the Borla, MagnaFlow, and Corsa options while still full stainless
- X-pipe design is a genuine engineering feature, not just a marketing term
- Only covers the 2011-2014 body style, not the current-generation Charger
MRT Street Race Axle-Back Exhaust (92G158)
An axle-back rather than full cat-back — MRT’s system for the 2015-2023 V6 Charger replaces only the rear section behind the resonator, which is a cheaper and easier install if you don’t need a full cat-back swap.
- Axle-back only (keeps the factory resonator/midpipe)
- Polished dual tips
- 2015-2023 3.6L Charger fitment
- Cheaper and faster to install than a full cat-back since it doesn’t touch the midpipe
- Good option if you like the factory sound up front and just want a louder rear section
- Smaller sound and flow change than a true cat-back since more of the stock system stays in place
Buying tips
- Match the part number to your exact model year, not just “Charger V6” — the 2011-2014 and 2015-2023 body styles use different exhaust systems even within the same brand and trim.
- If highway drone is your main worry, prioritize Corsa’s RSC or MagnaFlow’s straight-through mufflers over the louder Flowmaster or ATAK tunes.
- Cat-back systems replace everything from the catalytic converter back, so they don’t require tuning or throw a check-engine light the way header or downpipe swaps can. An axle-back (like the MRT) replaces even less, so budget your expectations for sound change accordingly.
