If you want to skip the comparison and go straight to a matched kit for your platform, the all-in-one delete kits collection covers Powerstroke, Cummins, Duramax and EcoDiesel with the pipe, tuner and EGR hardware bundled together.
Where Separate Parts Win
Buying piece by piece is the right call in three situations, and none of them are about the sticker price alone.
You already own some components. If you installed a delete pipe last year and it's still good, or you bought a tuner for a previous truck that carries over to your current one, there's no reason to pay for a full kit that duplicates what's already in your driveway. Buy the piece you're missing.
You want a specific brand for one part. Some owners have a strong preference on tuner brand, EFILive versus a handheld unit, or want a particular pipe material a bundled kit doesn't offer in their exact ching lets you get the exact combination you want instead of accepting a pre-set bundle.
Budget spread over time. A pipe this paycheck, a tuner next owners working within a tight budget. It costs more in total than buying it all at once as a kit, but it spreads the outlay across weeks instead of one large charge.
Where All-in-One Wins
For most first-time delete buyers, the bundled kit wins on more than convenience.
Compatibility is pre-solved. The pipe diameter, the tuner's supported year range, and the EGR block-off plates are matched to the same platform
before the kit ships. You're not cross-referencing three sping they agree.
One shipment, one arrival date. No waiting on a second box before you can start the install. Everything shows up together, which matters if you've
set aside a weekend to do the work.
One support contact if something's wrong. A missing bolt or a wrong-diameter reducer means one call, not three separate sellers pointing at each
other. That single-point accountability is worth more than usually need it.
Bundle pricing versus a la carte. Sourced individually, a pipe, tuner and EGR kit carry separate shipping charges and separate markup on each piece. Bundled, the combined price is almost always lower than the same three parts bought one at a time, since the seller isn't shipping and packaging each component on its own.
The Compatibility Failures That Cost the Most
This is where buying separately actually costs more than the kit price difference suggests, because the failures show up mid-install, not at
checkout.
Tuner that doesn't support your year. Tuner compatibility isn't universal even within one engine family. A tuner built for 2013 to 2018 Cummins
won't necessarily talk to a 2019-plus truck with the newer buy the tuner before checking that detail, you've bought a paperweight. Cross-check the exact model year before ordering from tuners, not after.
Pipe that doesn't match your cab and bed. Diesel pickups come in enough cab and bed length combinations that a delete pipe cut for a crew cab short bed can be the wrong length for a regular cab long bed on the same model year. Order by exact configuration, not just by engine and year. Current fitment options are listed under delete pipes.
Missing hardware discovered mid-install. This is the most common separate-parts mistake. A bare pipe kit ships with the pipe and clamps for that pipe only, not the gaskets, hose reducers or brackets the EGR side needs. Owners find this out with the truck already apart, and a $15 gasket
becomes a two-day delay waiting on a second shipment. If yr from individual listings, order every gasket and clamp up front rather than assuming it's included. Browsing the general diesel delete kit lineup before you buy component by component is worth the ten
minutes it takes to compare what each listing actually inc
What's Actually Inside an EngineGo All-in-One Kit
Using a current 6.7 Powerstroke all-in-one kit as the example, here's what ships in one box:
Tuner. A handheld delete tuner preloaded with delete-specport if you want a custom calibration later.
Delete pipe. A mandrel-bent pipe cut to factory dimensions for your specific cab and bed configuration, sold as either a straight pipe or a pipe
with a muffler depending on the kit variant.
EGR delete kit. CNC-machined block-off plates for the coolature reroute hoses, and the fittings that connect them.
Hardware and fittings. Clamps, gaskets and the bolts the install actually needs, so you're not making a second parts-store run partway through.
That's the entire point of buying it as one kit instead of three separate purchases: every piece is already confirmed to fit the same truck and work with the same tune.
Who Should Buy Which
Buy an all-in-one kit if: this is your first delete, you darts, or you'd rather pay slightly more up front than deal with fitment guesswork and a second shipment. If you've never done exhaust-side work on a diesel before, what it means to delete and tune a diesel truck is worth reading before you order anything.
Buy parts separately if: you already have a working pipe brand preference on one component, or you're deliberately spreading the purchase across paychecks and are comfortable double-checking fitment on each piece yourself.
Either path gets the job done. The difference is how much fitment research you're willing to do yourself versus paying to have it done for you.
Legal Notice: Off-Road and Competition Use Only
Diesel delete parts, pipes, EGR and DPF delete hardware, and related tuning, are sold for off-road, competition and closed-course use only. Removing or disabling emissions control equipment on a vehicle operated on public roads violates the federal Clean Air Act and may violate state and local law. Verify the rules in your state before you order, and don't install delete hardware on a truck you plan to drive on public roads.
FAQ
Is an all-in-one delete kit cheaper than buying parts separately?
Usually, yes. Bundled pricing on a matched pipe, tuner and EGR kit is almost always lower than the combined cost of buying the same three parts from separate listings, since the shipping and markup only apply once.
Can I mix a separately bought tuner with a bundled pipe and EGR kit?
You can, as long as the tuner supports your exact engine compatibility against your VIN before assuming it will work with parts bought elsewhere.
What's the biggest risk of buying parts separately?
Missing hardware. Gaskets, reducers and brackets are easy to leave off an order when you're buying pipe, tuner and EGR components from three different listings, and that's the gap that stalls an install halfway through.
Do all-in-one kits include tuning?
Most do, in the form of a handheld tuner with preloaded delete tunes. Confirm the specific kit includes a tuner rather than pipe and EGR hardware only before you order.
Should I compare this against just replacing the OEM DPF instead of deleting it?
That's a separate financial question worth running the nums OEM DPF replacement cost for the side-by-side breakdown.For the full delete cost picture including labor, How Much Does a Diesel Delete Cost in 2026? walks through every line item.
