Quick Comparison — Axle-Backs
Important
What to Know Before You Buy
Cat-Back vs Axle-Back
A cat-back replaces the mid-pipe and mufflers from the catalytic converter back. More performance gain, full system upgrade. An axle-back replaces only the mufflers and tips from the rear axle back. Lower cost, easier install, less performance gain. Both install behind the cats and are 50-state emissions legal.
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 Sport, CORSA Xtreme) 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. Aluminized is lowest cost; expect shorter life in salt climates. For long-term ownership, 304 SS is the better choice.
Emissions & Warranty
Cat-back and axle-back systems install behind the factory catalytic converters, so they’re 50-state emissions legal. No tuning required. Check manufacturer warranty — CORSA and Flowmaster offer limited lifetime coverage on many systems.
MBRP Cat Back Exhaust System (Aluminized): Chrysler 300 (15-24) / Dodge Charger (15-16) 5.7L Hemi
MBRP’s Cat Back Exhaust is the most affordable cat-back in this guide. The aluminized system delivers a street-friendly tone with improved flow over stock.

Aluminized construction keeps cost down but is less corrosion-resistant than 304 stainless. Fine for dry climates; consider 409 or 304 SS if you drive in salt. MBRP offers a 3-year warranty. Bolt-on installation using factory hanger locations.
Pros
- Lowest-priced cat-back in this guide
- Direct bolt-on; 3-year warranty

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 tips (mid-pipe + mufflers + tips). More performance gain, full system. An axle-back replaces only the mufflers and tips from the rear axle back. Lower cost, easier install, less performance gain. Both are 50-state emissions legal.
Will an aftermarket exhaust void my warranty?
Cat-back and axle-back systems install behind the factory catalytic converters and do not affect emissions equipment. They generally do not void the vehicle warranty. Modifications that alter emissions (headers, removing cats) can affect warranty. Check with your dealer if concerned.
Do exhaust systems add horsepower?
Yes. Cat-back systems typically add 5–15 HP and similar torque by reducing backpressure and improving flow. Axle-backs add less (often 2–5 HP) since they don’t replace the mid-pipe. Gains vary by vehicle and system.
What causes exhaust drone and how do I avoid it?
Drone is resonance at certain RPMs (often 1,500–2,500) that amplifies inside the cabin. Aggressive mufflers and straight-through designs can increase drone. CORSA’s RSC technology and Borla’s designs reduce or eliminate it. Research sound clips and reviews before buying.
304 vs 409 stainless steel: which is better?
304 stainless is more corrosion-resistant and premium; better for long-term ownership and salt climates. 409 stainless is budget-friendly and durable; fine for most conditions. Aluminized is lowest cost; expect shorter life in harsh environments.
I have a Hellcat Charger. What exhaust fits?
Several options: Cat-backs: JBA, Flowmaster American Thunder 392/Hellcat, Borla ATAK (392-specific; Hellcat has separate SKU), CORSA Xtreme, CORSA Sport. Axle-backs: MagnaFlow Race Series 19235. All fit 6.2L Hellcat Charger (2015–2023). Check each product for exact fitment.
