A Mild, Bolt-On Tone Upgrade Built To Fit Right

If you want your 2019-2026 Ram 2500 or 3500 6.7L Cummins to sound a little more purposeful without going overboard, the aFe Power Large Bore-HD DPF-Back Exhaust strikes that balance. Built from 5 inch mandrel-bent 409 stainless steel tubing, this system replaces everything from the DPF back with a mild, deeper tone that's noticeable without becoming obnoxious on long highway stretches. The system installs as a direct bolt-on using factory style hangers, so there's no cutting, welding, or permanent modification needed to get it in place. aFe designs every Large Bore-HD system using computer-aided design technology specifically for this platform, which means the fitment tolerances are tight and the install goes smoothly without fighting misaligned hangers or gaps. Finishing off the system is a 7 inch diameter polished stainless steel clamp-on exhaust tip, riveted with an aFe logo plate for a distinctive look at the rear of the truck. Every joint is 100% MIG-welded for genuine strength and long-term durability, not just spot welded for looks. For a straightforward exhaust upgrade built from true stainless construction, this system delivers both long-term corrosion resistance and a clean, polished finish.

Precision Stainless Steel Construction Engineered For Factory-Style Fitment

The aFe Power 49-42075-P Large Bore-HD DPF-Back Exhaust System is engineered specifically for 2019-2026 Ram 2500 and 3500 Crew Cab, Long Bed trucks with an 8 foot box and 169 inch wheelbase, equipped with the 6.7L Cummins engine. The system is constructed from 5 inch mandrel-bent 409 stainless steel tubing, 100% MIG-welded throughout for race-proven strength and durability rather than relying on spot welds at critical joints. Exit location is passenger rear, finished with a 7 inch diameter polished stainless steel clamp-on exhaust tip featuring a riveted aFe POWER logo plate. This system does not include a muffler, and sound level is rated mild, making it a subtle tone upgrade rather than an aggressive, drone-heavy setup. Installation uses factory style hangers for a secure, direct bolt-on fit, with all necessary hardware included and no cutting or modification required. Every Large Bore-HD exhaust system is engineered and manufactured at aFe's Corona, California facility. This product does not require a CARB EO number.
