Best Cat-Back Exhausts for the Dodge Challenger (2015–2023)

The Dodge Challenger's LC platform is one of the last body-on-frame-era muscle car holdouts in the modern era — and that means the exhaust note is load-bearing to the experience. Whether you're running a 5.7L RT, a 6.4L 392, or a supercharged Hellcat/Redeye, the factory system chokes real sound and leaves real power on the table. A cat-back won't touch emissions, won't require a tune, and transforms the character of the car faster than almost any other bolt-on. What separates a good Challenger cat-back from a loud one: pipe diameter matched to displacement, tip exit that clears the rear fascia (quad tips are a must on wide-body cars), and drone characteristics that matter if this is a daily. Here are the strongest options in the catalog, ranked for real-world use.

1. MagnaFlow 2017+ Dodge Challenger 409 SS Polished 3in Quad Tips Cat-Back — 19367

MagnaFlow 19367 — $1639

MagnaFlow's straight-through perforated core design is one of the most documented setups on Challenger forums for good reason: it adds meaningful sound without the rasp that straight-pipe setups bring at cruising RPM. The 409 stainless construction and polished quad tips are production-quality, and the 3-inch diameter is properly matched to post-cat flow on the 2017+ HEMI. This is the workhorse pick — it fits the widebody body lines cleanly and holds up without corrosion concerns in freeze-state climates. If you want a system that sounds correct and doesn't require maintenance, start here.

2. Corsa 15-21 Challenger SRT/Hellcat/Demon/Redeye 2.75in Valved Cat-Back w/ Twin 3.5in Polished Pro Tips — 21070

Corsa 21070 — $2400

If you're running a Hellcat, Demon, or Redeye, this is the purpose-built system. Corsa's Patented Reflective Sound Cancellation technology eliminates drone on the highway without baffles or restriction — it's acoustically quiet at part-throttle and violent at WOT, which is exactly what a 700+ hp car should do. The valved design lets you switch modes, and the 3.5in polished Pro Tips fill the rear fascia correctly on supercharged models. At this power level, valved systems aren't a gimmick — they're the difference between a car you can drive daily and one that exhausts you (pun intended). One of the most owner-validated picks in the Hellcat community.

3. AWE Tuning 2015+ Dodge Challenger 6.4L/6.2L SC Track Edition — Quad Diamond Black Tips

AWE Tuning SC Track Edition — Quad Diamond Black Tips — $1970

AWE's Track Edition is built for 6.2L and 6.4L owners who want maximum sound without compromise. Non-resonated construction means this system doesn't soften the HEMI's character — what you hear at idle and under load is the engine speaking without translation. The diamond black tips are a legitimate aesthetic upgrade over polished on dark-painted or matte-wrapped Challengers, and AWE's 304 stainless construction is among the best in the segment. If your build prioritizes sound character over daily comfort and you want a black tip finish, this is the pick over the Touring Edition.

4. Corsa 15-22 Dodge Challenger 6.2L/6.4L Xtreme Valved 2.75in Cat-Back Dual Rear Exit GTX2 Tips — 21068

Corsa 21068 — $1989

The broader 2015-2022 coverage makes this the valved Corsa option for 6.2L and 6.4L owners who want mode switching without paying the Hellcat-specific premium. GTX2 tips have a distinct appearance versus the polished round Pro tips on the 21070, and the Xtreme tuning means it's louder than Corsa's Sport offerings. Corsa's drone-elimination tech still applies here, so you're getting aggressive sound without sacrificing road trip usability. Strong pick for 392 SRT owners who want valved flexibility and a slightly different tip aesthetic.

5. AWE Tuning 2015+ Dodge Challenger 6.4L/6.2L Non-Resonated Touring Edition — Quad Silver Tips

AWE Tuning Touring Edition — Quad Silver Tips — $2118

AWE's Touring Edition threads the needle between aggressive and livable better than most systems at this price. Non-resonated means it still has real sound, but the Touring tune is calibrated to minimize the frequencies that create fatigue on long drives. If the Challenger is a weekend car that occasionally doubles as a road trip vehicle, this is the right call over the Track Edition. Quad silver tips pair cleanly with most OEM Challenger color options, especially B5 Blue and Torred builds. AWE's quality control on their exhaust systems is consistently praised across owner communities.

6. AWE Tuning 2015+ Dodge Challenger 6.4L/6.2L Non-Resonated Touring Edition — Quad Black Tips

AWE Tuning Touring Edition — Quad Black Tips — $2115

Functionally identical to the silver-tip Touring Edition above — same pipe diameter, same tuning, same AWE construction — the black tips here are the deciding variable. Pitch-black Challengers, Destroyer Grey cars, and any matte-wrapped build look significantly better with black tips over polished or silver. The price is nearly identical, so this decision is purely aesthetic. Both AWE Touring variants include AWE's no-drone guarantee and are backed by a lifetime warranty, which is a meaningful differentiator at this price point.

7. Corsa 17-18 Dodge Challenger 5.7L V8 Xtreme Cat-Back Dual Rear Exit w/ 3.5in Black Tips — 21006BLK

Corsa 21006BLK — $2450

The 5.7L RT is the most common Challenger on the road, and it's consistently underserved by the exhaust market — most manufacturers focus catalog development on the 392 and Hellcat. Corsa's Xtreme tuning for the 5.7L is specifically calibrated for that engine's exhaust characteristics, which are fundamentally different from the larger displacements. The black 3.5in tips match the aggressive rear exit look of upgraded 5.7L builds without looking undersized. Year-range is 2017-2018 specifically — confirm your model year before purchasing.

8. BBK 09-20 Dodge Challenger/Charger 5.7L Hemi 3in Mid Pipe w/ Converters — 40461

BBK 40461 Mid Pipe w/ Converters — $638

This isn't a cat-back — it's the mid-pipe section that most builds overlook. The factory mid-pipe on 5.7L Challengers and Chargers is a bottleneck that any serious cat-back upgrade will fight against. BBK's 3-inch mandrel-bent replacement retains catalytic converters (emissions-legal) while opening up the restriction between the headers and your cat-back. Pair this with any of the cat-backs above on a 5.7L build and you're getting the full exhaust system working together. At $638 it's one of the highest value-per-dollar modifications on the 5.7L platform and it's consistently recommended in RT-specific build threads as a prerequisite before spending $2000+ on a cat-back alone.

How to choose the best cat-back exhaust for your Dodge Challenger

Match the system to your engine, not just your car. The 5.7L, 6.4L, 6.2L Hellcat, and 6.2L Redeye all have different exhaust valve configurations, pipe diameter requirements, and tone characteristics. A system tuned for one will not perform optimally on another. Check fitment down to the engine code before purchasing.

Valved vs. non-valved. Valved systems (Corsa's primary differentiator in this catalog) give you on-demand volume control — quiet-ish at cruise, aggressive under load. If you daily the car or have noise ordinances to navigate, the premium for a valved system is worth it. If this is a weekend or track car, non-valved non-resonated systems like AWE's Track Edition deliver the cleaner tone without the added complexity.

Tip style and body configuration. Narrow-body and wide-body Challengers have different rear fascia openings. Quad tip systems are designed for wide-body applications and look proportionally correct. Dual tip systems on a wide-body look undersized. Confirm your body style when selecting tip configuration.

Stainless grade matters for longevity. 409 stainless (MagnaFlow's spec) is a ferritic grade — more economical, performs well in most climates. 304 stainless (AWE's spec) is austenitic, more corrosion-resistant, and preferred for northern climates where road salt is a factor. If you're keeping the car long-term in a freeze state, 304 is the better investment.

Don't skip the mid-pipe on 5.7L builds. The factory 5.7L mid-pipe is a documented restriction. Before spending $2000 on a cat-back, confirm whether your mid-pipe has been addressed. The BBK 3in mid pipe at $638 is a prerequisite mod that makes every cat-back perform better on this platform.

If you're building out the full exterior alongside the exhaust, check out our wheels catalog — the LC platform runs a 5x115 bolt pattern and responds well to 20x9.5 and 20x10.5 staggered setups on the widebody. Also worth reading: our S550 Mustang coilover guide for context on how muscle car suspension mods interact with the overall build, and our WRX cat-back guide for comparison on how different platforms approach the same category. Our Mustang generations piece is also worth reading if you're cross-shopping American muscle platforms.

FAQ

Do I need a tune after installing a cat-back exhaust on my Dodge Challenger?

No. Cat-back exhausts replace the system downstream of the catalytic converters and do not alter air/fuel ratio in a way that requires ECU recalibration. A tune is not required and the factory ECU will not throw codes from a cat-back alone. Headers or high-flow cats are a different conversation.

Will any of these systems fit both narrow-body and wide-body Challengers?

Some systems are designed for one or the other — confirm the specific fitment notes on each product page. Quad tip exits are proportioned for wide-body applications. Running a quad-tip wide-body system on a narrow-body car will result in tips that protrude or sit incorrectly relative to the rear bumper cutouts.

What's the difference between the AWE Touring Edition and Track Edition for the Challenger?

Both are non-resonated and built on the same 304 stainless construction. The Touring Edition is tuned to minimize drone frequencies at highway cruise while still delivering a strong HEMI note. The Track Edition removes that tuning entirely — it's louder, more aggressive at all RPMs, and prioritizes sound character over daily comfort. If you're doing long highway miles, Touring. If the car rarely sees highway, Track.

Is the Corsa valved system compatible with the factory active exhaust on Hellcat models?

The Corsa valved systems listed here replace the factory exhaust system including any OEM valve mechanisms. Corsa's valve system operates independently via the included controller or vehicle mode (depending on integration). Confirm with the product fitment notes for your specific model year, as the 2021+ Redeye has different OEM exhaust architecture than earlier Hellcat variants.
