DPF and EGR Delete on a 6.7 Powerstroke: Which Pipe or Exhaust Fits Your Year

Read the year off your door sticker before you read anything else on this page. On this platform the parts are bracketed by model year, and the bracket your truck sits in decides which ones bolt up. Get that detail wrong and the rest of the order is wrong with it.

Here's the thing — a delete pipe and a full exhaust are not the same purchase. A lot of guys assume any section they bolt in does the same job. One replaces a section in the middle. The other replaces the whole run from the downpipe back, and it costs accordingly.

Then there's the part nobody wants to hear: the tune goes on first. Not after. Pull the hardware off a truck still running factory calibration and you are chasing codes on a rig you can't drive off the lift.

Let's break it down. Which kit covers which years. What each one actually replaces. What the filter was doing before it came off, what shows up in the box, and where the EGR side fits into the same afternoon.

You already know the emissions hardware is this platform's Achilles heel. So let's get the fitment right, then talk about diameter.

Which DPF Delete Fits Your 6.7 Powerstroke?

The DPF & CAT Delete Pipe for 2011-2016 fits F-250, F-350 and F-450 pickups with the 6.7L Powerstroke. It lists from $399.00 to $564.00. The 2017-2019 pipe covers those same trucks. It carries the same price band. The 4" Exhaust DPF Delete spans 2011 through 2019. That system lists from $679.00 to $749.00. The 5" Exhaust DPF Delete covers the same years. It lists from $749.00 to $824.00.

Reading the model year off your own truck

Open the driver's door and read the sticker on the jamb. That is the number the fitment is bracketed against — not the year you bought it, not the year on the paperwork. Trucks built late in one year and titled in the next catch people out constantly.

The full-length systems are the easy half of this. One family, the whole run of model years, nothing to cross-check. It fits 2011 through 2019 F-250, F-350, and F-450 Super Duty pickups with the 6.7L Powerstroke, across all cab and box lengths. The pipes are where the split lives, and that is the part worth slowing down for.

Where the pickup fitment list stops

Cab and chassis trucks are the exception here, and they are the exception on every part on this page. The frame behind the cab runs differently, so the exhaust has to run differently too. There is no clever workaround.

It does not fit Cab & Chassis trucks, which need custom routing, and it doesn't fit 6.0L or 6.4L engines. Same story one diameter up. It does not fit Cab & Chassis models without modification, and it does not fit 6.0L or 6.4L Powerstroke engines.

If you are on a 6.0 or a 6.4, none of this applies. Different platform, different parts, different conversation.

What the 2016 to 2017 split actually changes

Two pipes, one break point. Cross it and the part changes. The DPF & CAT Delete Pipe for the 2017-2019 Ford 6.7L Powerstroke removes the Diesel Particulate Filter (DPF) and Catalytic Converter (CAT) from your exhaust system, our best-selling Powerstroke delete pipe. It's compatible with the F-250, F-350, and F-450 across the 2017, 2018, and 2019 model years with the 6.7L Powerstroke.

Earlier trucks get their own part. Fits 2011, 2012, 2013, 2014, 2015, and 2016 Ford F-250, F-350, and F-450 with the 6.7L Powerstroke. So which bracket does your truck sit in? Answer that and the budget answer arrives with it.

Does a Delete Pipe Replace Your Whole Exhaust?

The DPF & CAT Delete Pipe is not a full exhaust system. The CAT and the DPF are the two barrel shaped parts in your exhaust near the middle of your truck. Your factory muffler stays in place. The 4" Exhaust DPF Delete fits 2011 through 2019 pickups instead.

Finding the two barrel shaped parts under your own truck

Get under there with a light before you spend a dollar. Follow the pipe back from the turbo and you will run into two fat canisters. That is the section that comes off.

A DPF and CAT delete pipe only replaces the section of your factory exhaust that contains the emissions parts. Everything ahead of it and everything behind it stays where the factory put it. Ten minutes on the floor beats an hour on your back later.

What stays bolted on when only the pipe comes off

This is the half buyers get wrong, and it is an expensive assumption to make from a product photo. This pipe drops the two biggest restrictions in the factory exhaust: the DPF and the CAT.

The later bracket does the same job with the same steel. It eliminates both the DPF and the CAT and replaces them with a T-409 stainless steel section, while your factory muffler stays in place. So the truck opens up, and the can back there is still in the loop. That is a different sound to a straight run.

Why the full-length route is a different job

Fixing one restriction and leaving the rest is like patching one side of a leaky roof. The gas still has to squeeze through whatever the factory left behind it. The 4" DPF Delete Exhaust for the 2011–2019 Ford 6.7 Powerstroke pulls the Diesel Particulate Filter (DPF) and catalytic converter (CAT) off your F-250, F-350, or F-450 Super Duty.

That is a bigger afternoon and a bigger invoice. It is also the version where nothing downstream is still choking the engine.

What Is the DPF Actually Doing Before You Take It Off?

The DPF forces your engine into regen cycles, burning extra fuel at high temperatures to incinerate trapped soot. The DPF system is not capable of self-cleaning at idle.^[1] During self-cleaning there will be a change in the exhaust sound and engine idle speed.^[1] Without DPF backpressure, your turbo spools faster and EGTs drop under load.

What a regen cycle costs you in fuel

A regen is not a fault. It is the filter doing exactly what it was designed to do, on fuel you already paid for, at temperatures that cook everything around the pipe. Those cycles kill MPG and stress the engine, and they fail eventually anyway.

That last part is what stings. You feed the thing for years and it still ends up as a bill. A 4" delete pipe eliminates all of it. That ends the regen cycles, heat buildup, and backpressure that rob your truck of power and fuel economy.

Why idle time is the worst case

A truck that spends its life at low load is the worst case for this hardware. A staged build sitting between rounds is exactly that truck. Under certain conditions, such as idling or very short trips, the self-cleaning process has less efficiency and cannot be completed.^[1]

So soot loads up while nothing burns it off. Then the truck goes hunting for a cycle at the worst possible moment, and you feel it before any gauge tells you — the idle picks up and the note changes.

Backpressure, spool and exhaust gas temperature

Think about where the energy is actually going. To operate effectively and safely, the engine must continuously deliver air, fuel and lubrication to the cylinders. In a diesel engine, internal combustion results in expansion of high-temperature, high-pressure gases, which in turn move pistons.^[2]

What is left over heads out the exhaust and spins the turbine, and that is the free power in the whole system. Not every turbo handles that gas the same way. The types are differentiated based on how the exhaust gas is manipulated before it reaches the turbine wheel. In Fixed Geometry Turbochargers, exhaust gas flows through the volute in the turbine housing, directing 100% of it to the turbine wheel.^[3]

Every restriction between the head and that wheel is energy you bought and never used. Take it out and the turbine sees the gas sooner. That is the entire mechanism, and it is why a 6.7 build starts on the exhaust side.

Should You Run the 4-Inch or the 5-Inch Exhaust?

The 4" Exhaust DPF Delete lists from $679.00 to $749.00. The 5" Exhaust DPF Delete lists from $749.00 to $824.00. It fits all cab and box lengths. The OEM-style hangers and clamps bolt to factory locations, and the T-409 stainless steel handles real heat cycles.

4" Exhaust DPF Delete | Ford Powerstroke 6.7L 2011-2019

For most 2011 through 2019 pickups, the 4" Exhaust DPF Delete is the one to run. It is the better bang for your buck on a truck that is not chasing a class record, and there is simply less of it to route under a bed that already has things bolted to it.

Nothing else to source.

5" Exhaust DPF Delete | Ford 6.7L Powerstroke 2011-2019

On a heavily worked sled-pull or dyno truck, the 5" Exhaust DPF Delete is the call for 2011 through 2019 trucks. The 5" DPF Delete Exhaust for the 2011-2019 Ford 6.7 Powerstroke replaces the factory DPF (Diesel Particulate Filter) and CAT (Catalytic Converter) with a straight-flowing 5" T-409 stainless steel pipe, stopping the regen cycles, restricted exhaust flow, and EGT spikes that bog these engines down over time. Want the most restriction gone? That is the one.

When the smaller diameter is the right call

Most of these trucks are not making the power that needs five inches of pipe. They are stock-turbo builds with a tune and a set of injectors, and the smaller system flows more than they will ever ask of it.

This is a 4" high-quality T409 stainless steel exhaust that connects from the downpipe and runs the full length of the truck, replacing the OEM DPF and CAT sections with a straight, free-flowing pipe. If you've already got a delete tune running or you're planning one, this is the matching exhaust that finishes the job. Same steel, same hangers, less pipe to route. That is the whole trade.

What the larger diameter changes about the routing

Go up a size and the run has to be planned rather than dropped in. It runs from the down pipe connection straight back to the tailpipe, replacing the DPF, CAT, and all mid-pipe sections so your exhaust flows freely. Nothing in the middle survives that.

That changes what you have to check first. On a rig with airbags, a spare, or anything else living under the bed, walk the route with a tape before the box gets opened.

How loud you are willing to be

This is a real decision input, not an afterthought. A deleted 6.7 with nothing left in the middle is a beast at part throttle and a lot to live with in the pits.

Removing the DPF and CAT also opens up the exhaust note, so ask about muffler options if you want it quieter. The good news? That choice stays open after the pipe is on.

What Comes in the Box?

The 4" Exhaust DPF Delete fits 2011 through 2019. It comes with the full exhaust, the hangers and clamps, and a step-by-step installation guide. The 5" Exhaust DPF Delete covers those years too. You get the 5" T-409 down-pipe-back pipe, OEM-style hangers and clamps, all mounting hardware, and a step-by-step guide. The DPF & CAT Delete Pipe covers 2011 through 2016.

DPF & CAT Delete Pipe | Ford Powerstroke 2011-2016

You get the T-409 stainless delete pipe and a step-by-step installation guide, plus a full-time support staff if you hit a snag — open a ticket on our site any time. Shipping is included in the price.

DPF & CAT Delete Pipe | Ford Powerstroke 2017-2019

You get the delete pipe, the hangers and clamps, and a step-by-step guide. The pipe is built from high-quality T-409 stainless steel with OEM-style hangers and clamps for a factory-fit install, and shipping is included in the price.

Hardware versus a bare pipe

There is a real difference between a box with a pipe in it and a box with a pipe, the hangers, the clamps and the paperwork. One of those has you back at the parts counter halfway through. It's built from high-quality T-409 stainless steel with OEM-style hangers and clamps, so it bolts up to factory locations for a clean install.

Nothing here needs fabricating. Lay it out on the floor next to the old section and the two should mirror each other.

The one part you still have to source yourself

Hardware is only half the job, and this is the half that gets skipped. You'll want a compatible delete tune to keep DPF codes away.

So budget for the calibration alongside the pipe, not after it. We get it — nobody likes adding a line to the order. The alternative is a truck on the lift with a lit dash and an afternoon gone.

What Do You Need Before You Start the Install?

The first thing to do is verify you have all the parts. Your parts may look slightly different depending on the version you got. If you are missing any parts or have doubts, take a picture of everything you have received. Install the delete tuner first, always. You'll also need a compatible delete tune to prevent check engine codes after install.

The parts check that takes five minutes

Cut the box open the day it lands, not the morning you planned to work. Lay every piece out on the floor and count it against the guide. Two versions of the same pipe can look different and both be right, so count parts rather than matching photos.

We send a step-by-step instruction guide and keep a full-time support staff on hand for install questions, and you can open a support ticket on our website if you hit a snag. One photo of everything laid out answers the question in a single message instead of four.

Why the tune goes on first

This is the sequence that costs money when it is backwards. After installing the tuner, you can start removing the hard parts.

Do it the other way and the truck is sitting on stands with hardware off and no calibration to load. Now you are troubleshooting two problems at once, and one of them is your own doing.

What to have on the bench before the truck goes up

Penetrating oil the night before, on every clamp and hanger you can reach. A decent set of extensions. Something to cut a seized bolt with if it comes to that, because on a truck that has seen a few winters it usually does.

Your install instructions are there to view and download. Print them, because reading a PDF on a phone from under a truck is nobody's idea of a good time. There are a few installation videos to reference. Watch the first one, then move onto the others if you need more information.

You'll want a compatible delete tune to keep check engine codes away once the hardware is gone — call us and we'll help you pair the right one. Have it loaded and confirmed before a single bolt moves.

What Should You Expect During Installation?

The front end of the delete pipe connects to your down-pipe. The tail end connects to the tail pipe, just before the bend over the rear axle. The 4" Exhaust DPF Delete is the straight bolt-in on a 2011 through 2016 pickup. OEM-style hangers and clamps lock it in the same way the factory exhaust did, so there's no cutting, no fabrication, and no welding.

The order to work in, front to back

Start at the front and work back. Support the section before you free the last hanger, because the old assembly is heavier than it looks hanging up there. The delete pipe is the same diameter of your factory exhaust system, so it will be a perfect fit.

Install bolts up at the factory down pipe and hanger points with no welding, and you'll need a compatible delete tune to clear DPF-related codes from your ECM. Hang everything loose first, then walk the length and tighten. Chase your clearances before torque, or you will be loosening it all again.

Where a muffler goes if you are running one

Keeping a can in the loop is a common call. Fit it dry, mark it, then commit. A muffler that ends up an inch off is a muffler that rattles against the frame for the next two years. Nobody wants to be back under there in a month chasing a noise they built themselves.

Measuring before you cut anything

Most of these go on with no cutting at all. Bed length is the one variable that changes that. Depending on your truck bed, you may need to cut your pipe to modify your pipe length for fitment. Make sure to measure twice before cutting.

Tape, marker, then the saw, in that order. A pipe cut short is a pipe you buy again.

Where Does the EGR Side Fit Into the Build?

You do not have to delete the physical EGR. The sensors are what you remove on the physical EGR. The pipe has to be removed. These pipes are designed for pickup models and are not designed to fit Cab & Chassis trucks without modification, so call (888) 830-2588 Ext 2 or email sales@thedieseldudes.com for Cab & Chassis questions.

Hardware off versus sensors off

This is where the two halves of the job separate, and it is simpler than most people expect. The physical hardware can stay bolted to the engine. The plumbing is what actually comes out.

The exhaust needs to be deleted.

That half is not optional if the hardware is coming off, and it is the half people try to stage across two weekends.

Why the sequence is the same either way

Same rule as the exhaust side, and for the same reason. Having the DPF&CAT and EGR kit off your truck without the delete will trigger codes on your truck.

The calibration wants a truck with no codes present. Strip both sides first and you have handed yourself a puzzle instead of a build. Tune, then EGR, then pipe — every time.

When to make the call instead of guessing

Not sure which bracket fits your cab? That is a phone call, not a coin flip. Cab and chassis, an odd bed length, a truck that has already been apart once — those are the ones worth confirming before a box ships. Five minutes on the phone is cheaper than a return you cannot make.

What Happens After You Order?

Orders process within 1 business day. Standard shipping runs 8–10 business days, and upgrading to express speed takes 5–8. Alaska, Hawaii, and some Canadian locations may see additional freight charges, and if the pipe is on back order your shipment can take a few extra weeks. Exhaust systems are final sale, but a faulty or wrong product gets replaced, and tech support is included at (888) 830-2588 or sales@thedieseldudes.com.

How long the wait actually is

Processing and transit are two different clocks, and people run them together. Orders process within one business day, with standard shipping (included) in 8-10 business days and express in 5-8. Free shipping is included.

So plan the afternoon around the tracking number, not the order confirmation. If a build has a date on it, order two weeks out and sleep fine.

What final sale does and does not cover

Straight answer, because this is the one that surprises people. Exhaust systems and DPF/CAT delete pipes are final sale, but a faulty or wrong product gets replaced. Delete pipes are final sale and not eligible for a refund or return — but if you receive a faulty or wrong product, we'll send you a replacement.

So a wrong bracket is on you and a wrong shipment is on us. That is exactly why the fitment sits at the top of this page instead of the bottom.
