Important
What to Know Before You Buy
Engine-Specific Fitment
The 2019–2026 Ram 2500 uses 6.4L 392 Hemi (gasoline) and 6.7L Cummins diesel. Exhaust fitment is engine-specific. 6.4L systems do not fit 6.7L; diesel filter-back systems do not fit gasoline. Verify your engine before ordering.
Cat-Back vs Filter-Back
A cat-back replaces exhaust from the catalytic converter back (gasoline). A filter-back replaces exhaust from the diesel particulate filter back (6.7L Cummins). Both are 50-state emissions legal.
Trim & Cab Config
Some 6.4L systems are trim-specific. Gibson Dual Extreme fits Big Horn. MBRP Dual Split is 2500 only. Borla S-Type fits all cab/bed configs except dually. MagnaFlow Filter-Back 17912 is for 6.7L Ram 3500; verify 2500 6.7L compatibility.
Materials: 304 vs 409 vs Aluminized
304 stainless is most corrosion-resistant. 409 stainless is a step up from aluminized. Aluminized is budget-friendly. Borla and MagnaFlow use 304; Flowmaster and MBRP offer 409.

Common Questions
Frequently Asked Questions
What’s the difference between cat-back and filter-back?
A cat-back replaces exhaust from the catalytic converter back (gasoline). A filter-back replaces exhaust from the diesel particulate filter back (6.7L Cummins). Both are 50-state legal.
Will an aftermarket exhaust void my warranty?
Cat-back and filter-back systems install behind 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. Expect modest gains (5–15 HP / lb-ft) and improved throttle response. Diesel filter-backs can improve turbo spool.
What causes exhaust drone and how do I avoid it?
Drone is resonance at certain RPMs. Borla S-Type is designed for drone-free cruising. MBRP Dual Split can drone. Flowmaster Flow FX and MagnaFlow offer moderate tones.
304 vs 409 stainless: which is better?
304 stainless is more corrosion-resistant. 409 stainless is a step up from aluminized. Aluminized is budget-friendly; shorter life in salt climates.
I have a 2019 Ram 2500 6.4L. What fits?
MBRP, Flowmaster Flow FX, Borla S-Type, and MagnaFlow Street 15333 all fit 2019+ Ram 2500 6.4L. MBRP Dual Split is 2500 only. Borla excludes dually. Gibson Dual Extreme is Big Horn trim; verify 2019+ compatibility.
