Important
What to Know Before You Buy
Cat-Back vs Axle-Back
This generation has cat-back only options. A cat-back replaces the mid-pipe and mufflers from the catalytic converter back. Full system upgrade, more performance gain. Both 5.7L Hemi and 6.1L SRT8 have dedicated systems; fitment varies by engine.
Sound Profile & Drone
Aggressive systems can drone at highway cruise. CORSA’s RSC (Reflective Sound Cancellation) and Borla’s designs reduce drone. Research sound clips and reviews before buying. Drone-free options (CORSA Extreme, Borla S-Type) cost more but improve daily drivability.
Materials: 304 vs 409 Stainless
304 stainless is more corrosion-resistant and premium. 409 stainless is budget-friendly and still durable. For long-term ownership in salt climates, 304 SS is the better choice. JBA, Flowmaster, and MBRP use 409; Borla, MagnaFlow, aFe, and CORSA use 304.
Emissions & Warranty
Cat-back systems install behind the factory catalytic converters, so they’re 50-state emissions legal. No tuning required. Borla offers Million-Mile Warranty; CORSA, Flowmaster, and MBRP offer limited lifetime coverage on many systems.
JBA Cat-Back Exhaust System: Dodge Challenger 5.7L Hemi 2009 – 2014
JBA’s Cat-Back Exhaust is the most affordable option in this guide. The mandrel-bent 409 stainless system delivers a sport-oriented tone for 2009–2014 Dodge Challenger 5.7L Hemi. Dual rear exit with polished chrome tips. USA-made with a reputation for fitment. Bolt-on installation using factory hanger locations.
409 stainless keeps cost down but is less corrosion-resistant than 304. Fine for dry climates; consider 304 SS if you drive in salt. Fits 2009–2014 Challenger 5.7L Hemi (covers 2008–2010). Does not fit 6.1L SRT8 — JBA offers a separate SKU (40-1665) for that.
Pros
- Lowest-priced cat-back in this guide
- USA-made; bolt-on install
- Sport sound; 5.7L Hemi fitment
Cons
- 409 SS; less corrosion-resistant
- 5.7L only; 6.1L SRT8 has separate kit

Common Questions
Frequently Asked Questions
What’s the difference between cat-back and axle-back exhausts?
A cat-back replaces everything from the catalytic converter to the tailpipes (mid-pipe + mufflers + tips). An axle-back replaces only the mufflers and tips. This generation has cat-back only. Cat-backs offer more performance gain; axle-backs are cheaper and easier to install.
Will an aftermarket exhaust void my warranty?
Cat-back systems install behind the factory catalytic converters and do not affect emissions equipment. They generally do not void your powertrain warranty. Modifications to the engine, ECU, or emissions components can affect warranty coverage.
Do exhaust systems add horsepower?
Yes. Reducing backpressure and improving flow can yield 5–15 HP and similar torque gains, depending on the system and engine. aFe, CORSA, and Borla publish dyno results. Gains are typically modest but noticeable in throttle response.
What causes exhaust drone and how do I avoid it?
Drone is resonance at certain RPMs (often 1,800–2,500) during cruising. Systems with X-pipes, resonators, or acoustic tuning (CORSA RSC, Borla) reduce it. Avoid the loudest “race” profiles if you drive long distances.
304 vs 409 stainless steel: which is better?
304 stainless is more corrosion-resistant and premium. 409 stainless is budget-friendly and adequate for most climates. For salt-belt or long-term ownership, 304 is the better choice.
I have a 6.1L SRT8. What are my options?
CORSA Extreme (14438), Borla (140286), aFe MACH Force-Xp (49-42028), Stainless Works, MagnaFlow (16885), MBRP Pro Series (S7110304), and JBA (40-1665) all offer SRT8-specific cat-backs. CORSA and Borla are the top choices for drone-free cruising.
