Ram Cummins 6.7 Full Delete Bundle: The 2013-2018 Build Guide

What Is the Ram Cummins 6.7 Full Delete Bundle?

The Ram Cummins 6.7 Full Delete Bundle is built around the Cummins 6.7L engine. The 6.7 Cummins Full Delete Kit for the 2013-2018 Ram 2500 and 3500, Mega Cab included, permanently removes the DPF (Diesel Particulate Filter), DEF (Diesel Exhaust Fluid) system, EGR, and CAT from your truck's ECM. Nearly 70% of all Ram 2500 and 3500 Heavy Duty pickup owners choose the Cummins Turbo Diesel.^[1]

You already know the feeling. The truck is staged, the tune is written, and the factory emissions hardware is still bolted to it. That hardware is where most builds on this platform stop.

The problem the package is built to solve on a competition truck

A lot of guys start by pulling one piece. The filter comes out, a pipe goes in, and the ECM still thinks the old hardware is sitting there. Here's the thing: a pipe alone is not a kit. Deleting the filter and leaving the recirculation loop alone is like fixing a leaky roof on one side of the house and ignoring the other.

So the package treats it as one job. Software and hardware, matched to your bracket. That is the whole idea.

Hardware and tune as one purchase instead of two

This platform has history behind it, and that history is why the parts market for it runs so deep. Cummins engines have been an option in RAM pickups since 1989.^[4] Cummins has gone from 5.9-liter, 160-horsepower beginnings to the 6.7-liter, 400-horsepower engines.^[4] Same basic inline-six, getting stronger every generation. Ram was the first to achieve the 1,000 lb.-ft. of torque milestone with the Cummins I-6 Turbo Diesel, now rated at a best-in-class 1,075 lb.-ft. of torque.^[3] This high-output (HO) rating is offered exclusively in the RAM 3500 equipped with the Aisin transmission option.^[2]

That longevity cuts both ways. There is a part for everything, which also means there is a wrong part for everything. Piece a build together from four suppliers and the day something does not line up, nobody owns it.

How to read the rest of this guide

Fitment comes next, because that is the part that costs real money when you get it wrong. After that: what is in the boxes, which tuner to pick, what the factory parts were doing in the first place, how the install actually goes, and what lands in your inbox afterward. Skip ahead if you already know your bracket. The verdict is at the bottom.

Which Trucks Does the 2013-2018 Bundle Fit?

The Ram Cummins 6.7 Full Delete Bundle covers model years 2013, 2014, 2015, 2016, 2017 and 2018 on the Cummins 6.7L. It fits the 2013 through 2018 Ram 6.7L 2500 and 3500 across all pickup trims and box lengths, but not Cab & Chassis trucks. The install instruction sets work on pickup models.

Reading the model year and model off your own truck

Which bracket does your truck sit in? Two minutes at the door jamb sticker settles it. Model year first, then the 2500 or 3500 badge, then confirm the 6.7L under the hood.

Model year and build year are not the same thing, and that catches people out more than any other detail on this list. Read the sticker. It takes longer to unbox the wrong kit than to walk out and look.

Where this fitment list stops

Cab & Chassis is the hard edge here. On Cab and Chassis models the instruction sets require minor modifications. That is not a small footnote when you are already on your back with the old pipe hanging.

If your truck wears a flatbed that came off the factory floor, confirm the model line before anything else moves. The engine is the same. The frame behind the cab is not, and that is what the instructions are drawn against.

Trims and box lengths that are all covered by one part number

The good news? Trim and box length do not split this part number. Short bed, long bed, Mega Cab, Crew Cab, base truck or loaded truck, it is the same kit. This platform does not make life easy very often, so take the win.

Still not certain which bracket your truck falls in? Call (888) 830-2588 and read the door jamb sticker out loud to whoever picks up. Two minutes on the phone beats a weekend with a kit that does not bolt on.

What Comes in the Full Delete Bundle?

The Ram Cummins 6.7 Full Delete Bundle pairs a tuner and rotary switch with a 4-inch Rust Resistant DPF & CAT Delete Pipe and a Complete EGR Delete Kit. A Delete Tune is included. An Optional Muffler System is offered. You choose between two bundles.

The parts check to run before you touch a wrench

The boxes land and the temptation is to start swinging. Don't. The first thing you should do is verify you have all the parts.

Lay it all out on the floor beside the truck and tick it against the list before a single factory bolt comes loose. Gaskets and hardware are the pieces that go missing, and they are also the pieces that stop the job dead at nine on a Sunday night. Ten minutes on the floor beats an hour on your back.

Hardware versus software: two halves of one job

No cutting and no welding, since both use bolts and clamps that we provide. That one fact is what puts this job inside a home shop instead of a fab shop.

Hand tools, a way to get the truck in the air, and patience with rusted fasteners will cover it. No torch. No welder. If you have ever changed an exhaust on this platform, you already have everything the hardware side asks for.

What is optional and what is not

Both pair a tuner with a rotary switch, the 4" DPF and CAT delete pipe, and the complete EGR delete kit, with an optional 5" exhaust and muffler available. So the core of the kit never changes between the two versions.

What changes is the exhaust you take with it. Want the truck quieter in the pits between rounds? That is what the muffler line is there for. Leave it off and the truck gets loud in a way you will hear from the far end of the staging lanes.

EZ Lynk or EFI Live: Which Tuner Should You Choose?

The difference is the tuner: EZ Lynk ships preloaded and plug-and-play through the AutoAgent phone app, while EFI Live's software is emailed and loads from a Windows 10 or 11 computer. EZ Lynk runs five: Stock, +40HP, +80HP, +120HP, and +160HP. EFI Live runs four power settings: Stock, +65HP, +100HP, and +130HP. Both tuner versions fit the same trucks, right up to the 2018 model year.

Phone app or laptop: what each one asks of you

This is the one real decision in the whole package. One tuner option is an Ez Lynk tuner with preloaded delete tunes and all required accessories, with a rotary switch to change power levels. The other tuner option is an EFI Live tuner and delete tune software that is not preloaded, with all required accessories and a rotary switch to change power levels.

We get it, nobody wants to babysit a laptop in a cold shop in February. If that sentence describes your shop, the phone-app route decides itself. If you would rather have a real screen and a keyboard in front of you while a revision loads, go the other way and never think about it again.

How many power steps you actually use on a build

Most builds live on two settings. One for the pass, one for everything else.

The extra steps earn their keep while you are shaking a truck down, and after that they mostly sit there untouched. So do not pick your tuner on step count. Pick it on how the tune reaches the truck, because that is the part you deal with every single time a revision comes through.

The 2018 unlock cable, and why it comes first

Read this part twice if your truck needs the cable. The cable is meant to be installed and left in the vehicle, not intended to be uninstalled and re-used. The cable has to be installed again if tune revisions are ever required.

So install it once and leave it alone. Pulling it back out only means doing the same job over the next time a revision lands, usually the week before an event when you have the least patience for it.

What Do the Factory Emissions Parts Actually Do?

Within the 6.7-liter Dodge Ram Heavy Duty exhaust system, reducing particulate matter is achieved through a self-cleaning Diesel Particulate Filter.^[6] Decreasing NOx emissions is a next-generation cooled Exhaust Gas Recirculation (EGR) system.^[6] Variable Geometry Turbochargers (VGT) work by varying the exhaust passage area before the exhaust gas entry into the turbine wheel.^[5]

Where each factory part physically sits

Picture the path the gas takes and the layout stops being a mystery. The EGR system is water cooled, with the air reintroduced into the intake system, keeping turbo and intercooler components clean.^[6]

So the loop runs off one side of the engine and back into the intake on the other. Everything else lives downstream, further along the exhaust. That stretch is exactly where the delete pipe goes. Picture it as a circuit and the job stops being abstract.

Why these parts run hot and stay dirty

VGTs offer versatile optimization across engine speeds and loads, aiding engine braking, exhaust gas recirculation and thermal management.^[5] Thermal management is the phrase to sit with for a second.

Treat these parts as one system rather than four separate bolt-on components. That is the mental model that makes the rest of the job obvious, and it is the reason the tune is not an optional extra you can add later.

What the tune has to be told once the hardware is gone

Strip it back to first principles. In diesel engines, internal combustion results in expansion of high-temperature, high-pressure gases, which in turn move pistons, transforming chemical energy into mechanical energy.^[8] To operate effectively and safely, the engine must continuously deliver air, fuel and lubrication to the cylinders.^[8] In a common rail setup, diesel fuel is stored in a high-pressure rail that supplies fuel to each injector independently.^[7]

The ECM is what keeps those deliveries in step with each other. Change what is bolted to the engine and the ECM has to be told about it. That is the whole job the delete tune does, and it is why it goes on first.

What Should You Expect During Installation?

The delete tune reprograms your ECM to run without the emissions systems, then you remove the hardware. The kit's 4-inch pipe is the Rust Resistant DPF & CAT Delete Pipe. The front end of the delete pipe connects to your down-pipe and the tail end of the delete pipe connects to the tail pipe, just before the bend over the rear axle.

The tools and the lift time the job really wants

Hand tools, a long breaker bar, and penetrating oil sprayed the night before. That last one is not a joke on a truck that has spent a decade in mud and hard use.

A lift turns this into a comfortable afternoon. Jack stands turn it into a long one. Budget more time than the install video suggests, because the truck in the video was clean and yours has been to the trail.

The order to work in, and what happens if you invert it

Tune first. Always. The 4" rust-resistant DPF and CAT delete pipe bolts in where the factory units were, and the EGR delete kit seals off the EGR passages so hot exhaust gases stop recirculating into your intake.

Invert that order and you are standing under a truck that is already apart, staring at a dash full of lights, with nothing to load. Let's break it down as simply as it goes: software, then wrenches.

Measuring before you cut anything

Depending on your truck bed, you may need to cut your pipe to modify your pipe length for fitment. Please make sure to measure twice before cutting!

Mock the entire run up loose first, hangers and clamps included, and only then mark the pipe. Let it hang on its own weight for a minute before you commit. A pipe cut short is not a pipe you can uncut.

What to check once everything is back together

Walk the full length of the exhaust and hold a hand near every joint at idle. Clamps settle on the first heat cycle, so plan on going back around them once the truck has been up to temperature and cooled again.

2013-2018 Ram Cummins EGR delete instructions are available. Read them end to end before the first fastener comes out, not halfway through when something in your hand does not match the photo.

What Happens After You Place the Order?

After purchase you'll get a vehicle info form, and we need 2-3 days to process your custom tune. On returns: tuners and exhaust are non-refundable, and the EGR kit is returnable unused within 30 days with a $30 restocking fee. Your parts may look slightly different depending on the version you got.

Filling out the vehicle info form without a second round trip

Have the VIN in front of you before you open the form. Transmission, tire size, axle ratio, and whatever hard parts are already on the truck all change what gets written.

An incomplete form is what sends the whole thing back a round. Send it complete the first time and the clock actually starts that day instead of three days later.

Planning the build week around the tune turnaround

Waiting is the worst part of any build, and this is a short wait with an obvious use for it. Soak the fasteners. Clear the bench. Lay the exhaust out in the order it goes on, so you are not scrambling at the parts store mid-install.

By the time the tune lands in your inbox, the truck should already be sitting there ready for it. That is how a two-day turnaround costs you nothing at all.

What is returnable and what is not

Read the return terms before you commit, not after. A tune is written to your specific truck, which is exactly why it cannot go back on a shelf and be sold to somebody else.

The hardware side is different. Keep the EGR kit boxed and unopened if there is any real chance the build changes direction, and you keep your options open.

Is the Full Delete Bundle Worth It for Your Build?

The Ram Cummins 6.7 Full Delete Bundle is listed at $1932.00 to $2959.00. Both include transmission tuning, and most owners report a 5 mpg increase on average. "See Dealer" codes, check engine lights, and limp mode are gone. The latest generation Cummins 6.7L Turbo Diesel is a heavy-duty pickup engine.^[9]

What the price covers versus buying the pieces separately

Price the pieces one at a time and the gap closes faster than you would think. A pipe from here, a kit from there, a tuner from a third place, and a tune written by whoever answers the phone that afternoon.

Then something does not line up. Now you have four suppliers and none of them owns the problem, while your truck sits on stands taking up the only bay you have. One part number. One support thread. That is worth real money at exactly the wrong moment.

Ram Cummins 6.7 Full Delete Bundle | 2013-2018

Two choices left: which tuner, and whether the larger exhaust goes on with it.

Who this build is right for, and who should stop here

For a 2013 through 2018 Ram 2500 or 3500 running the Cummins 6.7L, the Ram Cummins 6.7 Full Delete Bundle is the one to buy. It suits a truck that already has a job in front of it. A sled-pull rig, a dyno truck, a trail build that spends its weekends where the ruts are.

If none of that describes your truck, this is not where to start. A workhorse doing exactly what you ask of it does not need a full package thrown at it, and there is no shame in leaving it alone.

The one decision left once you have read this far

Fitment is settled by a sticker on your door jamb. The contents are the same in both versions. So the only real question left is how you want the tune to reach the truck. A phone in your pocket, or a laptop on the bench.

Answer that one and the rest is a Saturday and a set of hand tools.
