6.7 Cummins Exhaust Systems

These are turbo-back and downpipe-back systems, most bundled with the delete hardware and tuning.

2013-2017 Ram 2500/3500, 4" turbo-back: the most common choice for stock-turbo trucks.
2013-2017 Ram 2500/3500, 5" turbo-back with muffler: larger diameter with the muffler kept in place.
2013-2017 Ram 2500/3500, 4" DPF delete with muffler: shorter section rather than a full turbo-back run.
2013-2017 6.7L Cummins, 4" turbo-back: turbo-back without the throttle valve component.
2013-2017 6.7L Cummins, 4" DPF delete with muffler: the quieter shorter-run option.

How to Pick Diameter and Muffler

Start with diameter. A 4" system suits stock and lightly modified 6.7L Cummins trucks and keeps the setup reasonable for towing and daily driving. A 5" system gives more room on trucks making real power, though on an otherwise stock truck the extra diameter buys you volume more than anything measurable. Then decide on the muffler. Owners who tow, drive daily, or spend time in the truck generally keep it, since a muffler-less 5" system on a work truck gets old quickly. Dedicated off-road and race builds often skip it. Last, decide where the system starts. A turbo-back replaces everything from the turbo. A downpipe-back or shorter delete section replaces less and costs less. Cab and Chassis 4500 and 5500 trucks route differently than pickups, so check your body style.

Why Ram Owners Order Exhaust From EngineGo

Exhaust is where hanger placement and cab configuration quietly decide whether a system bolts up. Every listing states the years, the truck models, the diameter, and whether a muffler is included, along with what hardware comes in the box. Orders ship from U.S. warehouses, most process the same or next business day excluding Sundays, and free shipping applies within the continental United States. Authorized returns are accepted within 45 calendar days on qualifying items, and installed exhaust is generally not returnable, so confirm fitment first. Send your year, model, cab style, bed length, and current setup and we will check it.

Shop 6.7 Cummins Exhaust Systems

Pick your diameter based on how the truck is built, decide on the muffler based on how you drive it, then match the year range. If you are torn between 4" and 5" on a stock-turbo truck, message support and we will give you a straight answer rather than upselling you.

Important: Some products in this collection are intended for off-road, race, or non-public-road use where permitted. Confirm federal, state, and local laws before purchase and installation. Customers are responsible for legal compliance.
