For the 6.7L Cummins, this restriction traps heat near the exhaust manifold and turbocharger turbine wheel, leading to elevated Exhaust Gas Temperatures (EGTs) during sustained towing or heavy-load cycles. Over time, the OEM piping—which lacks the wall thickness of high-grade aftermarket alternatives—can suffer from resonant vibration and localized heat soak, ultimately limiting the engine's volumetric efficiency and throttle response.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis kit is constructed from heavy-duty 409 stainless steel with a 2mm wall thickness, providing a superior balance of corrosion resistance and structural integrity against diesel heat cycles. The system features 4.0-inch diameter piping that is TIG welded for maximum seam strength and utilizes CNC machined flanges for a precision fit against the turbo pipe. By eliminating unnecessary bungs and utilizing mandrel bends, the kit provides a smooth, unobstructed path for exhaust gases. The 4.0\" inlet diameter ensures a high-flow transition, while the clamp-on mounting style allows for a secure, leak-free installation on the driveway using basic hand tools. This configuration specifically addresses the round flange connection found on the turbo pipe of the updated Cummins I6 platform.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2019-2022 Ram 2500 \/ 3500\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e6.7L Cummins I6 \/ DJ (2500) - D2 (3500)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e370-427 HP \/ 850-1,075 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eu1833UB416EU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eYears:\u003c\/strong\u003e 2019-2021 Ram 2500\/3500 (Fits 2022 applications with matching flange)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfigurations:\u003c\/strong\u003e Crew Cab Short Bed, Crew Cab Long Bed, Mega Cab\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncompatibility:\u003c\/strong\u003e Not compatible with 3500\/4500\/5500 Cab \u0026amp; Chassis models\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncompatibility:\u003c\/strong\u003e Not compatible with vehicles equipped with factory air suspension systems\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRequirement:\u003c\/strong\u003e Fit Round flange off turbo pipe ONLY\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Ram Heavy Duty Standard\u003c\/h3\u003e\n\u003cp\u003eThe Ram 2500 and 3500 are built for extreme durability and heavy-duty towing; this exhaust upgrade supports those tasks by optimizing thermal management and reducing the parasitic loss caused by exhaust backpressure, ensuring the Cummins powerplant remains efficient under the heaviest loads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":47999045206264,"sku":"DS-E8NYNOBQM","price":289.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-pipes-for-dodge-ram-2500-3500-2019-2022-6-7l-cummins-1.webp?v=1771352938","url":"https:\/\/performancechiptuning.com\/products\/exhaust-pipes-for-dodge-ram-2500-3500-2019-2022-6-7l-cummins","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
