CCV Reroute Kit Buyer's Guide: Powerstroke, Cummins and Duramax
Oil film across the inside of the intercooler piping, oil pooling in the intake tract, and an intake system that looks like it needs cleaning every few thousand miles. That's the CCV system doing exactly what a factory-restricted design does over time, and it's the reason CCV reroute kits show up on nearly every serious diesel owner's upgrade list.
Here's what the reroute actually fixes, the symptoms that tell you it's time, what's inside a kit, and fitment by platform so you're ordering the right one the first time.

What Codes Appear After a Delete and What Each One Means
A check engine light two days after a delete feels like something went wrong. Most of the time it didn't. A handful of specific codes show up constantly after a DPF, EGR or DEF delete, and almost all of them trace back to one of four things: the tune, a disturbed sensor, a missed install step, or something that was never related to the delete in the first place.
This is the code-by-code breakdown, what triggers each one, what it means for your specific install, and which codes actually need attention versus which ones clear themselves once the tune finishes learning your truck.

Diesel Delete Install: Difficulty, Time and Tools by Platform
"How hard can it be" is the wrong question to start with. The better one is "how hard is it on my truck, with my tools, in my garage." A 6.7 Cummins delete on a lift with an impact gun is a different weekend than a 6.0 Powerstroke on jack stands with hand tools and rusted bolts that haven't moved since the truck left the factory.
This is the platform-by-platform breakdown: what the job actually involves, what it takes to do it right, and where most first-timers lose an entire day to something that shouldn't have taken twenty minutes.

All-in-One Delete Kit vs Buying Parts Separately: An Honest Comparison
Every diesel owner planning a delete hits the same fork in the road. Buy the pipe from one listing, the tuner from another, and the EGR hardware from a third, or order one kit that already has all three matched to the same truck. Neither choice is wrong. They just solve different problems, and picking the one that fits your situation is worth more than any single part number.
Here is the honest version, not the sales pitch: where separate parts genuinely save you money, where an all-in-one kit is worth paying for, and the compatibility mistakes that turn either choice into a bigger bill than you planned.

How Much Does a Diesel Delete Cost in 2026? Full Parts and Labor Breakdown
Everyone quotes a different number for a diesel delete, because everyone is pricing a different job. A delete pipe by itself is not the same purchase as a full DPF, EGR and tune package, and a shop quote that includes four hours of labor is not comparable to a driveway install with a borrowed jack.
So here is the number broken into its actual parts: what each line item costs on its own, what shops charge to install it, what owners forget to budget for, and what the total looks like once you add it all up by platform.

Delete Kit vs OEM DPF Replacement: The Real Cost Comparison
A service writer just handed you a number with three commas in it, and the truck is still sitting on the lift. That's the moment most diesel owners start Googling "DPF delete kit" instead of signing the repair order. Fair enough. But before you decide, it helps to see the real numbers side by side instead of guessing at what a shop quote actually includes.
An OEM DPF replacement and a DPF delete kit solve the same immediate problem (a filter that's derating your truck or throwing codes), but they cost different amounts up front, carry different long-term price tags, and come with very different odds of you facing this same bill again in eighteen months. Here's how the math actually breaks down.

Best Tuner for LML and LMM Duramax Complete Buyer's Guide
If you own a 2007.5-2010 LMM or a 2011-2016 LML Duramax, "best tuner" is not a one-size-fits-all question. Both engines share the 6.6L Duramax badge, but the fuel system, emissions hardware, and safe tuning limits are different enough that the same tune file can help one truck and hurt the other. Before you buy anything, confirm which generation you own, since the LMM and LML sit on opposite sides of a major fuel system change that decides how hard you can push the calibration.
Most owners searching "best tuner for Duramax" are really asking a narrower question without realizing it: what tuner works for my exact engine code, my fuel pump, and my emissions hardware. This guide breaks down what each platform supports, what a safe tune looks like, and how tuning pairs with a delete kit if you're building a truck for off-road or competition use. Start by browsing LML Duramax tuners if you already know your platform. If you're working with the earlier engine, browse LMM Duramax tuner options instead.

Best Tuner for the 6.7 Powerstroke by Model Year (2011-2024)
Not every 6.7 Powerstroke tuner works the same way across three generations of trucks. A tuner built around the 2011-2014 emissions setup will not calibrate the same way on a 2020-2024 truck, and buying based on engine size alone is one of the fastest ways to end up with the wrong package for your specific year. If you own an F-250, F-350, or F-450 with the 6.7L Power Stroke, matching the tuner to your exact model year, cab configuration, and emissions setup is the first real decision to get right.
This guide breaks down what actually works for each generation, what changed under the hood between them, and how to pair a tuner with the rest of your setup without wasting money on parts that do not talk to each other correctly.

Best Tuner for L5P Duramax: 2017-2024 Options Compared
If you own a 2017 to 2024 Chevy Silverado or GMC Sierra 2500/3500HD with the 6.6L L5P Duramax, you already know tuning this platform is not as simple as plugging in a handheld and picking a power level. GM built the L5P around a locked ECM, and that single decision changed how every tuner, unlock tool, and delete kit on the market has to work with this truck.
This guide breaks down the three real paths to tuning an L5P: unlocking with EFILive, unlocking with HP Tuners, or buying a turnkey unlocked package. We will cover what each option actually requires, what it costs when you add up every piece, and what will not work no matter how good the marketing sounds.

Handheld Tuner vs Custom Tune: Which Do You Actually Need?
You already know your diesel needs a tune. What you're stuck on is which kind. A handheld unit that arrives loaded with preset power levels, or a custom file built around your exact combination of parts. Both fix the same basic problem: a truck that's been modified but is still running factory calibration. But they solve it in different ways, at different price points, and for different builds.
Buy the wrong one and you either overpay for tuning flexibility you'll never use, or you undersize your setup and end up back at square one once you add the next part. Here's how to tell which category your build actually falls into.
The short version: if your truck is close to stock aside from a delete, a preloaded handheld tuner will cover you. If you've changed the turbo, injectors, or transmission behavior, you're in custom tune territory, and no amount of preset power levels will get the fueling and shift points right. If you already know which category you're in, you can shop tuner options for your platform now, or keep reading to confirm your build first.

Does My Truck Need an ECM Unlock? Platform-by-Platform Guide
If you have started shopping for a tuner and keep running into the term "ECM unlock," you are not alone. Late-model diesel trucks ship with locked engine control modules that block third-party tuning software until the lock is removed by an authorized process. Whether you need one depends entirely on your exact truck: year, make, engine, and sometimes the specific PCM hardware installed at the factory.
This guide breaks down which platforms need an unlock, which ones do not, what the process actually involves, and what it costs before you order a kit.

EFILive vs HP Tuners vs EZ Lynk vs MM3: Diesel Tuner Comparison
If your truck has been deleted or you are planning a delete, the tuner you choose matters as much as the pipe you run. A delete kit removes restriction. A tuner is what tells the engine computer how to run without the factory emissions logic in place. Pick the wrong platform for your truck and you end up with codes, poor drivability, or a device that cannot talk to your specific engine at all.
EFILive, HP Tuners, EZ Lynk, and MM3 are the four platforms that come up in almost every Powerstroke, Cummins, and Duramax forum thread. They are not interchangeable. Each one was built around a different engine family, a different support model, and a different way of paying for tunes. This guide breaks down what each platform actually does, which trucks it fits, and how to match it to your build before you order diesel tuners for your setup.

EcoDiesel Common Problems & Owner Upgrade Path
The 3.0L EcoDiesel in the Ram 1500 and Jeep Grand Cherokee gives owners real towing torque and better fuel economy than a comparable gas V8. It also carries a full set of emissions hardware, and that hardware is where most of the complaints start. If you searched for EcoDiesel problems because your truck is throwing codes, dropping into limp mode, or burning through oil faster than it should, this guide breaks down what actually fails, at what mileage, and what most owners do about it.

EcoDiesel DPF Delete Guide: 2014-2023 Ram 1500 and Grand Cherokee
If your 3.0L EcoDiesel drops into a regen cycle almost every time you pull out of the driveway, you already know the frustration. Ram 1500 and Jeep Grand Cherokee owners running the VM Motori 3.0L diesel deal with a DPF that loads faster than most half-ton diesel owners expect, especially when the truck spends more time in stop-and-go traffic than on the highway.
This guide covers why the EcoDiesel aftertreatment system struggles with short trips, what symptoms show up before a filter fails outright, and what a DPF delete kit actually replaces on this platform. Fitment differs between Ram 1500 and Grand Cherokee, so pay close attention to the year-by-year notes before you order anything.

4-Inch vs 5-Inch Delete Pipe: Which Diameter Is Right for Your Truck?
If you are shopping delete pipes and stuck between a 4-inch and a 5-inch diameter, you are not alone. It is one of the most common questions diesel owners ask before checkout, and the right answer depends on your truck's use, your tune, and how much drone you are willing to live with on the highway.
Diameter is not a spec you should pick based on what sounds biggest. It is a fitment and performance decision tied to your engine platform, your intended use, and whether you are running stock power or a build with real airflow demands. Get it wrong and you either leave flow on the table or end up with a setup that drones on every highway trip and costs more than you needed to spend.

Delete Pipe With Muffler vs Without: Sound, Drone and Towing Compared
Once you have picked your platform and your pipe diameter, one choice still stands between you and checkout: muffler or no muffler. It looks like a small option on the product page, but it changes how your truck sounds at idle, how it feels on a six-hour highway pull, and whether your passengers still want to ride with you after the first fill-up.
This is not a question with one right answer. It depends on how you actually drive the truck, not how loud you want it to sound in the driveway.
Quick recommendation by driving pattern:
Daily driver, highway commuter, or truck with regular passengers: keep the muffler.
Weekend truck, work rig with short local runs, or a build focused on tone over comfort: no muffler works fine.
Heavy tow rig doing long interstate miles: most owners in this camp keep the muffler for cabin comfort.
Track use, pulls, or dedicated off-road rig: no muffler is the common choice.
Both configurations are available across our delete pipe options, so the decision comes down to how the truck gets used, not what is in stock.

Aluminized vs Stainless Steel Delete Pipe: Which Lasts Longer?
If you are shopping for a delete pipe, the diameter and the DPF or EGR compatibility usually get all the attention. Material rarely comes up until year three, when an aluminized pipe that looked fine on install day starts showing surface rust around the welds and clamps. By then the question is not "which pipe fits" anymore. It is "why did I need to replace this so soon."
This guide breaks down aluminized steel, 409 stainless, and 304 stainless so you can pick a delete pipe that matches how long you plan to keep the truck, where you live, and how the truck gets used.
Quick pick: how long do you plan to keep the truck?
If you are keeping the truck less than three years, aluminized steel is usually fine and saves money up front. If you plan to keep it five years or more, or you tow and drive in a road salt state, 409 or 304 stainless pays for itself by avoiding a second install. Owners in coastal regions with constant salt air exposure get the longest service life out of 304 stainless specifically.

Downpipe vs Delete Pipe vs Up-Pipe: What Each Part Does and When You Need It
If you have spent any time shopping for diesel exhaust parts, you have probably seen these three terms used almost interchangeably. They are not the same part, they do not solve the same problem, and ordering the wrong one is one of the most common mistakes diesel owners make.
An up-pipe, a downpipe, and a delete pipe each sit in a different section of the exhaust path, and each one exists to fix a different issue. Some trucks only need one of these parts. Others need all three working together. This guide breaks down exactly what each part does, which platforms are known for problems in each section, and how to figure out what your specific truck actually needs before you order.
This confusion is not unique to first-time buyers either. Even owners who have been running a modified truck for years sometimes assume "downpipe" is a catch-all term for anything downstream of the turbo, or that a "delete" always includes every section of pipe from front to back. It does not. Getting this wrong usually means a return, a wasted install day, or a part sitting in the garage because it does not connect to anything on the truck.

Diesel Up-Pipe Upgrade Guide: Symptoms, Fitment, and What to Buy
If your 6.0L Power Stroke has gone soft on boost, smells like exhaust under the hood at idle, and leaves dry black soot around the turbo, a cracked up-pipe is one of the first things to check. It is a low-cost part that produces expensive-feeling symptoms, and most owners chase the turbo, the sensors, and the tune before they find it.
This guide covers what an up-pipe does, how a failing one behaves, how to confirm it before you spend money, and how to match a replacement to your exact truck. Fitment changes by engine family and year, so check your platform before you shop diesel up-pipes.

2018 vs 2019 6.7 Cummins: Why Delete Parts Are Not Interchangeable
One model year apart, two different trucks. A 2018 Ram 2500 and a 2019 Ram 2500 both run a 6.7L Cummins, and on paper they look close enough that owners assume parts swap between them. They do not.
2019 was a full generation change for Ram heavy duty. New body, new frame, revised aftertreatment routing, and a locked ECM that changed how tuning works on the entire platform. Buying a kit built for a 2017 and bolting it to a 2019 is one of the most common misorders in this category.
Here is what actually changed, what carries over, what does not, and how to confirm which side of the split your truck sits on before you order 2019-2024 6.7L Ram Cummins parts.

2011–2019 vs 2020–2024 6.7 Powerstroke: What Changed for Delete Parts
If you own a 6.7L Power Stroke and you are shopping for delete pipes, EGR kits, or tuners, the model year on your truck matters more than the engine badge. Ford kept the same displacement across both generations, but the fuel system, turbo, sensor layout, and tuning requirements are different enough that a part built for one truck will not bolt onto the other. Before you order anything, confirm which generation you own.

Duramax Delete Parts Interchange Guide: LB7, LLY, LBZ, LMM, LML, and L5P
"Duramax" is not one engine. It is six different engines built across 24 years of GM heavy-duty trucks, and the parts that fit one generation usually will not bolt onto the next. Owners run into this constantly: an EGR cooler pulled from a 2015 LML truck will not work on a 2007 LMM, a delete pipe cut for an LBZ exhaust will not clock correctly on an L5P, and a tuner license built for one ECM will not touch another.
The mistake is almost always the same. Someone shops by "Duramax" instead of shopping by engine code, orders a part that looks close enough, and finds out at install time that the flange spacing, sensor bungs, or ECM protocol are wrong. This guide breaks down what actually interchanges, what never does, and how to confirm which engine sits under your hood before you order.

6.7 Cummins Delete Tuner: Best Options for 2013–2024
If you're piecing together a 6.7L Cummins delete kit, the tuner is the part that decides whether the job actually works. A downpipe and an EGR delete kit change what's bolted to the engine. The tuner is what tells the ECU how to run once those parts are gone. Skip this step, or pick the wrong calibration for your model year, and you're looking at fault codes, a check-engine light, or the truck dropping into limp mode on the highway.
This guide breaks down what a delete tuner actually does, which options exist for the 2013–2024 Ram 2500 and 3500 with the 6.7L Cummins, and how to match the right tuner to your specific truck before you order anything.

Does Cab and Bed Configuration Change Which Delete Pipe You Need?
If you have started shopping for a delete pipe and noticed the same platform listed in multiple lengths, you already know the answer is yes. Two trucks with the identical engine, the same model year, and the same drivetrain can still need a different pipe once cab and bed configuration enter the picture. This is one of the most common reasons diesel owners order the wrong part and end up with a pipe that will not reach the tailpipe or clears the frame in the wrong spot.
This guide breaks down exactly what changes exhaust routing on Power Stroke, Cummins, and Duramax trucks, so you can confirm your setup before you check out instead of after the box arrives.

3.0L EcoDiesel Delete Kit Buyer's Guide: Ram 1500 and Jeep Grand Cherokee
This guide is written for 2014–2023 Ram 1500 EcoDiesel owners and 2014–2023 Jeep Grand Cherokee diesel owners running the 3.0L EcoDiesel V6. If your truck or SUV is throwing DEF-related codes, going into frequent regen, or facing an expensive aftertreatment repair quote, this is the platform breakdown you need before you shop EcoDiesel delete kits.
The EcoDiesel is not built like a heavy-duty Power Stroke, Cummins, or Duramax. It's a half-ton and SUV application, and the parts, install process, and expectations are different. Below is a quick fitment reference before you shop.

EcoDiesel EGR Delete Kit: What's Included and Fitment by Year
If your 3.0L EcoDiesel is throwing coolant on the ground, idling rough, or sitting on a diagnostic code tied to exhaust gas recirculation, you're probably already searching for a way out of the factory EGR system. This guide breaks down why EcoDiesel owners delete the EGR, what a proper EcoDiesel EGR delete kit actually includes, and which model years it fits before you order anything.

Best 6.7 Cummins Upgrades for Towing and MPG
Ask any diesel guy what truck to buy if you tow heavy, and the 6.7L Cummins is always in the conversation. That big inline-six makes its torque down low where towing lives — but a stock, emissions-equipped 6.7 Cummins leaves real towing capability and fuel economy on the table. The right upgrades fix both at once: a truck that tows cooler and more reliably and gives back MPG you're currently burning on regens and restrictions. This guide ranks the best 6.7 Cummins upgrades for towing and MPG, from the single biggest win to the supporting mods, plus a real-world strategy for squeezing out fuel economy.

L5P DPF Delete Pipe Buyer's Guide: What 2017–2024 Duramax Owners Need to Know
If you run a 2017–2024 Chevy Silverado or GMC Sierra 2500/3500 with the 6.6L L5P Duramax, the diesel particulate filter (DPF) is the single biggest restriction in your exhaust — and the source of most regen headaches, fuel-economy losses, and limp-mode scares. A L5P DPF delete pipe swaps that clogged, expensive factory filter for a straight, free-flowing pipe. This buyer's guide breaks down pipe diameters, materials, fitment by year, and the one thing you absolutely cannot skip: the tune.

LML EGR Delete Kit Buyer's Guide: Everything 2011–2016 Duramax Owners Need to Know
If you own a 2011–2016 Chevy Silverado or GMC Sierra 2500/3500 with the 6.6L LML Duramax, there's a good chance the EGR system is already costing you money — or about to. The LML's EGR cooler is one of the most failure-pro ne emissions parts on the truck, and once it goes, it can take your coolant, your intake, and your weekend with it. This LML EGR delete kit buyer's guide walks you through exactly what fails, what parts you actually ne ed, and how to pick a kit that bolts on right the first time.

LMM EGR Delete Kit Buyer's Guide: What 2007.5–2010 Duramax Owners Need to Know
If you own a 2007.5–2010 Chevy Silverado or GMC Sierra 2500HD/3500HD with the 6.6L LMM Duramax, the EGR system is one of the most common reasons these trucks end up in the shop. Carbon-fouled intakes, cracked EGR coolers, and coolant disappearing into the engine are all classic LMM problems — and they keep coming back as long as the EGR is in place. This LMM EGR delete kit buyer's guide covers what fails, the exact parts you need, and how to choose a kit that installs right the first time.
