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 — full performance gain, improved flow. An axle-back replaces mufflers and tips only — lower cost, easier install, less performance gain.
Sound Profile & Drone
Aggressive systems can drone at cruise. CORSA RSC® and Borla S-Type reduce cabin drone. MBRP Race Profile is loudest. Research sound clips before buying.
Engine-Specific Fitment
Durango fitment varies by engine: 3.6L V6, 5.7L Hemi, 6.4L SRT (2018+), 6.2L Hellcat (2021+). Most cat-backs are engine-specific. Axle-backs target 5.7L R/T. Verify your engine before ordering.
Emissions & Warranty
Cat-back and axle-back systems install behind the factory catalytic converters, so they’re 50-state emissions legal. Borla offers Million-Mile Warranty; Flowmaster has Lifetime Limited Warranty.

Common Questions
Frequently Asked Questions
What’s the difference between cat-back and axle-back exhausts?
A cat-back replaces the mid-pipe and mufflers from the catalytic converter back. An axle-back replaces mufflers and tips only. Cat-back = more performance gain; axle-back = lower cost, easier install.
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. Check with your dealer if concerned.
Do exhaust systems add horsepower?
Yes. Cat-back systems reduce backpressure and improve exhaust flow. CORSA reports up to 50.93% flow improvement. Expect 5–20 HP depending on the system and engine.
What causes exhaust drone and how do I avoid it?
Drone is resonance at certain RPMs. CORSA RSC® and Borla S-Type reduce cabin drone. MBRP Race Profile can drone at cruise. Research sound clips before buying.
I have a Durango Hellcat. What fits?
MBRP Aluminized cat-back fits the 6.2L Hellcat (2021+). Borla ATAK is 6.4L SRT only. Verify fitment for 6.2L Hellcat before ordering.
304 vs 409 stainless steel: which is better?
304 stainless is more corrosion-resistant and premium. 409 stainless is budget-friendly and still durable. For salt climates or long-term ownership, 304 SS is the better choice.
