2015 Ram 1500 Ecodiesel Delete Kit

What Is a 2015 Ram 1500 EcoDiesel Delete Kit?

The Ram 1500 is the light-duty pickup in the Ram lineup.^[1] The DPF & CAT Delete Pipe fits the 2015 Ram 1500 EcoDiesel. It pulls both the DPF and the CAT out of the exhaust stream and replaces them with a free-flowing T-409 stainless steel section. The EGR Delete fits the same truck.

Here's the thing — a delete on this platform is two jobs, not one. The exhaust side and the recirculation side are separate parts in separate boxes, and they come off the truck at different points underneath it. Handle one and ignore the other and you have finished half a build.

The two jobs a delete build splits into

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.^[2] That is the whole engine in one sentence. Everything else on this page is about the air moving in and out of it.

The first job is the exhaust path. Spent gas leaves the engine, runs back along the pipe, and passes through whatever the factory bolted into the middle of that run. The second job is the recirculation path, where a share of that same gas gets sent back toward the intake instead of continuing out the back of the truck.

Two paths, two parts. Keep them straight now and everything below reads easily.

Reading your own truck before you read a parts list

We get it — every parts list looks like it was written for somebody else's truck. Start with the badge and the build sheet. Model year first, engine second, body style third.

Miss any one of those three and the part in your hands will not match the truck on the stands. That is not the kind of mismatch you notice early. It is the kind you notice with the exhaust already unbolted and the afternoon already gone.

Which Delete Parts Fit Your 2015 Ram 1500 EcoDiesel?

The EGR Delete fits 2014 through 2018 Ram 1500 and Jeep Grand Cherokee with the 3.0L EcoDiesel. The DPF & CAT Delete Pipe fits the Ram 1500 across the same 2014 through 2018 years. The Jeep Grand Cherokee 3.0L delete exhaust covers Grand Cherokee models across the same 2014 to 2018 years.

Three rows, one bracket. Your model year sits dead center in all three of them, which is about as clean as a fitment answer gets.

Finding the model year on your own truck

Your door jamb sticker carries the build date and your title carries the model year. Read the model year rather than the build date. The bracket above runs on model years every single time.

Chrysler launched the Ram in 1981.^[3] Four decades of model years later, the badge on the tailgate tells you almost nothing about which parts bolt up — the year and the engine code do all the work.

Where this fitment list stops

Fits 2014, 2015, 2016, 2017, and 2018 Ram 1500 (full delete) and Jeep Grand Cherokee (valve-only) with the 3.0L EcoDiesel. Step one model year outside that window in either direction and you are looking at a different part number entirely. The bracket does not stretch.

That cuts both ways, and the good news is that it cuts in your favor here. Yours is not a borderline year on this platform. It is not sitting at either edge of the range, so nothing on this page is a near-enough match hoping to be close enough.

Ram 1500 and Grand Cherokee are not the same job

One kit covers both the Ram 1500 and the Jeep Grand Cherokee EcoDiesel, with one important difference: it's a full valve-and-cooler delete on the Ram, and a valve-only delete on the Jeep. Same box, same part number, two genuinely different jobs once the hood is up.

The exhaust side never merges like that. Whichever badge is on the fender decides which pipe is yours, and reading the wrong half of the instructions is an easy mistake to make when you are skimming rather than reading.

What Does the DPF & CAT Delete Pipe Actually Replace?

The DPF & CAT Delete Pipe only replaces the section of the factory exhaust that contains the emissions parts. The pipe is built from high-quality T-409 stainless steel with OEM-style hangers and clamps, so it bolts into the factory mounting points with no cutting, welding, or fabrication. The delete pipe is the same diameter as your factory exhaust system.

A lot of guys picture the whole exhaust coming off the truck when they hear the word delete. It doesn't. This is a section swap, and the section is shorter than most people expect.

Where the section starts and where it ends

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. Slide under the truck and you can trace the whole job with one hand before you touch a wrench.

That's the span you're working in. Everything ahead of the down-pipe stays. Everything behind that bend over the axle stays too.

What stays on the truck

Your factory muffler stays right where it is. Nothing behind the cab comes down, nothing gets cut to length, and nothing that was quiet before gets loud by accident.

Knowing that up front changes how you plan the afternoon. You are not dropping a full system and rebuilding it from the down-pipe back. You are pulling one barrel-shaped stretch out of the middle and putting a straight one back in its place, which is a very different amount of work than it sounds like from the name.

Why nothing needs to be cut or welded

Diameter is the whole reason this drops in clean. Match the factory pipe size and the hangers land where the factory hangers landed, so there's nothing to fabricate and nothing to guess at.

Ten minutes lining up factory mounting points beats an hour under the truck with a grinder and a tape measure. That's also why a universal pipe is a different animal — it fits everything on paper and nothing in particular underneath a specific truck.

What Does the EGR Delete Do on the 3.0L EcoDiesel?

A cooled Exhaust Gas Recirculation system works to decrease NOx emissions.^[4] The EGR Delete covers the EcoDiesel Ram and the Grand Cherokee. On the Ram this kit completely removes the EGR valve and cooler, seals the intake passages, and reroutes coolant flow. The hardware is built right: billet aluminum construction, nickel-plated steel flanges, a stainless steel bracket, high-temp silicone hoses, zinc-coated hardware, and precision O-rings.

Let's break it down, because this is the half of the build people underestimate. The pipe is a swap. This one is plumbing, sealing and hardware all at once.

The valve and the cooler are two separate parts

On the Jeep it deletes the valve only — the cooler stays. That one difference separates two builds that share a single part number, and it is worth reading twice before anything comes apart.

On the Ram, both pieces go. The valve and the cooler are two separate pieces of hardware sitting in the same path. Pulling one and leaving the other is like fixing the leaky side of a roof and walking away from the other side — you've done real work and the problem is still there.

What sealing the intake passages means in practice

Sealing the intake passages is part of the same job, and it is not a finishing touch. It is the step that decides whether the work holds.

That's why the sealing side of this job is worth more attention than it usually gets. Every piece in the hardware list above exists because something needed to be closed off properly, and it is built for a spot that sees constant heat cycling. Cheap out on the sealing hardware and the fastener or the O-ring is usually what lets go first, quietly, long before the part it was holding together does.

Coolant routing after the cooler comes off

Variable geometry turbochargers aid engine braking, exhaust gas recirculation and thermal management across engine speeds and loads.^[5] Heat is the through-line in all of it, which is exactly why the cooler was plumbed into the coolant circuit in the first place.

Take the cooler out and that circuit has a gap in it. Rerouting the flow is what closes the loop back up, and it is the reason the Ram build involves cooling lines rather than just fasteners. Budget the time for it. This is the step that turns a bolt-on afternoon into a proper job, and it is the one worth doing slowly.

What Comes in the Box With Each Part?

The DPF & CAT Delete Pipe fits the Ram. You get the delete pipe, the OEM-style hangers and clamps, and an installation guide in the box. The EGR Delete fits both the Ram and the Jeep. Everything needed for a complete install is in the box, and you only need basic tools. The Jeep Grand Cherokee 3.0L fits the Grand Cherokee.

Three parts, three boxes, three separate deliveries. Nothing here is a combined kit, so count each one on its own.

Unboxing check before anything comes off the truck

In the box: the delete pipe, the hangers and clamps, and an installation guide. Your factory muffler stays in place. Between those two lines you already know what to expect on the bench and what to leave alone under the truck.

Open every box the day it lands, not the morning you plan to work. Lay the hardware out on cardboard and count it against the guide while the truck is still whole. Ten minutes on the floor beats an hour on your back finding out a clamp never made it into the box.

What is not in the box

Basic tools are the assumption, not a specialty kit. If your toolbox already handles routine work on the truck, it handles this — that's bang for your buck on hardware built this seriously.

The tuning side of the job is a separate purchase. That is its own line item and its own step, and it gets its own section below because it is the one people skip. Treat the hardware and the tune as two halves of the same project rather than one order that quietly needed a second.

Do You Need a Tune Alongside These Parts?

The DPF & CAT Delete Pipe is the Ram-side pipe in this lineup. A compatible delete tune is required alongside the pipe to keep check engine codes from setting after install. The Jeep Grand Cherokee 3.0L is the Grand Cherokee pipe. A compatible delete tune is required to disable regen in the ECM before you install the pipe; the pipe alone won't remove emissions codes.

Yes. Short answer, and it's the same answer for every part on this page.

What the tune is actually doing

On the EGR Delete, plan the tune as part of the job rather than after it. The hardware changes what the engine is physically doing; the tune changes what the ECM expects it to be doing. Leave the second half undone and the two disagree with each other, loudly, in the form of codes.

A lot of guys assume the pipe alone gets them there. It doesn't, on either vehicle. Bolting on hardware and hoping the computer sorts itself out is how a good afternoon turns into a week of chasing lights.

Sequencing the tune against the hardware

Read the two lines above carefully, because they are not the same instruction. On the Grand Cherokee pipe the tune goes in first, before the pipe is installed. On the Ram pipe the tune runs alongside the install to keep codes from setting afterward.

Same requirement, two different orders of operation. Plan whichever one applies to your vehicle before the truck goes up, not after. Nothing on this page is harder to unwind than hardware that went on in the wrong sequence.

What Should You Expect During Installation?

The DPF & CAT Delete Pipe is made for the Ram. Delete kit instructions are sent by email after purchase. The written installation document can be viewed or downloaded for reference. Parts may look slightly different depending on the version you got. The first thing to do is verify you have all the parts shown.

That last one sounds obvious. It is also the step that gets skipped most often, and it is the cheapest ten minutes in the whole job.

The parts count before the first bolt

If any parts are missing or in doubt, take a picture of everything you have received. Do it before anything comes off the truck, while the layout still matches the guide. A photo of a complete bench is a much faster conversation than a description of a half-apart truck.

Count first, then read, then work. In that order, every time.

The order to work in

Read the whole guide before you pick up a tool. Not skim — read. Knowing what step four needs stops you from doing step two in a way that makes step four harder.

Work front to back on the exhaust side and top down on the recirculation side. Break every fastener loose before you fully remove any of them, because a bolt that fights you is much easier to argue with while the assembly is still supported. Have your replacement hardware laid out and within reach before the old section comes down, so you're not scrambling mid-job.

What to check before the old section comes off

It's a bolt-in replacement using OEM-style hangers and clamps that seat in the factory mounting positions, so there's no cutting, welding, or fabrication and no exhaust leaks or vibration. Your job is making sure the old section comes off as cleanly as the new one goes on, rather than fighting a seized clamp with the whole run hanging.

Support the pipe before you free the last hanger. Have a second set of hands for the awkward stretch. And give every fastener a shot of penetrant the night before if the truck has seen a few winters — a beast of a rust-welded clamp is the one thing that turns a two-hour job into a two-day one.

When to stop and ask

We send a step-by-step instruction guide and have a full-time support staff to answer any install questions, plus you can open a support ticket on our website if you run into issues. That is worth using before you improvise, not after.

Still not sure the part in your hands matches the guide in front of you? Call (888) 830-2588 and talk it through before anything comes off the truck. There is no prize for guessing, and a five-minute call is cheaper than a wrong part number and a truck on stands.

How Do These Parts Change the Way the Engine Breathes?

Variable Geometry Turbochargers work by varying the exhaust passage area before the exhaust gas entry into the turbine wheel.^[5] To operate effectively and safely, the engine must continuously deliver air, fuel and lubrication to the cylinders.^[2] In a common rail setup, diesel fuel is stored in a high-pressure rail that supplies fuel to each injector independently.^[6]

Two sides, one engine. Understanding both is what turns a parts list into a build you actually understand.

Exhaust side: passage area and the turbine wheel

This increases the pressure and velocity of the exhaust gas, which then boosts pressure and airflow to the engine as needed.^[5] That is the mechanism the whole exhaust side rests on — gas speed against a wheel, managed rather than fixed.

Everything bolted into the run behind that wheel is sitting in the same stream of gas. That is the picture worth carrying: one path, several things in it, each one shaping how the gas leaves.

Intake side: what the engine has to keep delivering

Common rail injectors deliver precise amounts of diesel fuel to the combustion chambers.^[6] This approach ensures a constant and consistent high pressure, allowing for precise control over fuel injection timing and quantity.^[6]

Air on one side, fuel on the other, both measured. That is why the tune matters as much as the hardware does — you have changed one side of a system that was calibrated around both. The exhaust side and the fuel side are separate systems on this engine, and nothing on this page touches the fuel side. It stays exactly as the factory built it.

Which Setup Should You Buy for Your Truck?

The DPF & CAT Delete Pipe is priced at $489.00. It fits 2014, 2015, 2016, 2017, and 2018 Ram 1500 with the 3.0L EcoDiesel, pickup models only. The EGR Delete is priced at $299.00. The Jeep Grand Cherokee 3.0L delete exhaust is priced at $709.00. Compatible with Jeep Grand Cherokee 3.0L models only, across the 2014, 2015, 2016, 2017, and 2018 model years.

The vehicle decides this, not the budget. Read the badge, then read the prices.

If you drive a 2015 Ram 1500

For a 2015 Ram 1500 with the 3.0L EcoDiesel, the DPF & CAT Delete Pipe is the exhaust-side part to run. On the same truck, the EGR Delete is the recirculation-side part to run. Neither one replaces the other, and neither one is a partial version of the other.

Run both if you want the full build. Run the pipe alone if the exhaust side is what you came for and the recirculation side can wait. What you should not do is buy the Grand Cherokee pipe because the engine badge matches — the engine is shared, the exhaust run underneath is not.

If you drive a Grand Cherokee

For a Grand Cherokee, the Jeep Grand Cherokee 3.0L delete exhaust is the pipe that fits. It is a separate product at a separate price, and the difference is the exhaust geometry under a different vehicle, not the engine in front of it.

The recirculation side is the more forgiving half here, since one kit already spans both vehicles. The exhaust side never merges back into a single answer. That is the one distinction worth carrying out of this page.

Ordering terms worth reading first

Free shipping; 30-day returns on unused kits. Shipping is included and orders process within one business day, with standard delivery in 8-10 business days and express in 5-8. Alaska, Hawaii, and some Canadian locations may see additional freight charges.

Exhaust systems and DPF/CAT delete pipes are final sale, but a faulty or wrong product gets a replacement. That matters more than it looks. Once a delete pipe is on the truck it is on the truck, so the fitment check at the top of this page is the step that keeps the order right.
