Picking up the 2007 6. 7 cummins delete kit is easily the biggest favor a person can do for your truck in case you're tired of coping with constant regen cycles and slow performance. If a person own one associated with these early 6. 7 engines, you know exactly what I'm speaking about. 2007 had been a bit of a weird yr for Dodge—it was the transition from the legendary (but aging) 5. nine to the very much beefier 6. 7 Liter. While the extra displacement was great for towing, it brought a whole new set of headaches thanks in order to the first generation of heavy-duty emissions gear.
The reality is that those early systems weren't exactly "refined. " They were basically the industry's first stab with meeting strict brand-new EPA standards, plus the result had been a truck that will felt like this was breathing through a wet sock. If you've already been on the fencing about whether the delete kit is definitely worth the effort, let's break down why so many proprietors end up going this particular route and exactly what you can in fact expect when you stop the soot from cycling back again through your consumption.
The Problem with Early 6. 7 Emissions
When the 6. 7 Cummins hit the particular scene in mid-2007, it introduced the Diesel Particulate Filtration system (DPF) and the Exhaust Gas Recirculation (EGR) system in order to the Ram collection. On paper, this sounded fine. The particular DPF catches soot, and the EGR lowers combustion temperatures to reduce NOx. In practice, however, these parts became the bane of each owner's existence.
The DPF is basically a large ceramic honeycomb in your exhaust tube. Over time, this fills up along with soot. To clean it, the truck will go into "regen" setting, which means it sprays extra diesel in to the exhaust to literally burn the soot out. Not really only does this particular kill your fuel economy, but if you do a lot of idling or short trips close to town, the DPF never gets hot enough to clean itself. That's when you obtain the dreaded "DPF Full" message as well as your truck goes into limp mode, leaving you stranded or crawling to the nearest dealer for any forced regen or perhaps a multi-thousand-dollar replacement.
What's Actually in the Kit?
When people talk about a 2007 6. 7 cummins delete kit, they will aren't just talking about one single part. It's a combination of hardware and software that functions together to make simpler the engine.
The Exhaust Pipe (DPF Delete)
This is the most apparent part. You're swapping out that enormous, heavy DPF plus the catalytic converter for a straight through pipe. This usually comes in 4-inch or 5-inch diameter options. It's significantly lighter, lets the particular turbo breathe, and—let's be honest—it can make the truck seem like a real diesel powered again.
EGR Block-off Plates
The EGR system takes hot, dirty exhaust and shoves it back into your own intake manifold. More than time, this produces a thick, oily sludge that coats your valves and intake. A delete kit includes plates to block those ports off. Some people just unplug the EGR, but a full delete eliminates the cooler and the plumbing completely, cleaning up the engine bay plus preventing coolant leaks, that are a common failure point on these trucks.
The Tuner (The Brains of the Operation)
You can't just rip the particular exhaust off plus expect the pickup truck to run. The engine's computer (the ECM) will freak out because it's looking for sensor readings from your DPF and EGR. This is exactly where a tuner arrives in. The tuner reflashes the ECM to tell this, "Hey, don't be concerned about those detectors; they aren't presently there anymore. " With out the tuner, your own truck will be stuck in a permanent limp mode.
Why Do People Actually Do It?
It isn't just about producing the truck even louder, though that's an excellent side effect for some. Most guys go for the 2007 6. seven cummins delete kit simply because they want their own truck to end up being reliable. Once you get rid of the DPF and EGR, you're removing the two nearly all common causes of check out engine lights and shop visits.
Beyond dependability, the performance jump is massive. Mainly because the engine isn't fighting against back pressure from a blocked filter, the turbocharged spoils up very much faster. You'll notice a significant bundle in throttle response. Most owners also report an raise of 2 in order to 4 miles per gallon once the truck halts wasting fuel on regen cycles. Over a few years of driving, those energy savings can really pay for the kit itself.
The Installation Process
If you're handy with the wrench, installing the delete kit is definitely a solid Saturday project. You don't need a raise, though it certainly makes things easier. The hardest component is usually working with rusty mounting bolts on the manufacturing plant exhaust. Since these trucks are getting older, those nuts and bolts possess seen a lot of warmth cycles and road salt.
Once the aged exhaust is away, the newest pipe usually slips right into place. The EGR delete can be a bit more tedious due to the tight spaces in the back of the engine near the firewall, but it's straightforward. The almost all nerve-wracking part regarding most people is definitely plugging in the particular tuner and waiting for the improvement bar to complete. Simply make sure your own batteries are completely charged before you start—you don't desire the truck in order to die in the middle of a software flash.
Let's Talk About the Legal Side
I'd be doing you the disservice basically didn't mention that removing a truck is definitely technically for "off-road use only. " The EPA offers been cracking down on emissions tampering for years, plus in many says, you won't complete an inspection in the event that your emissions equipment is missing.
Before a person pull the result in on a 2007 six. 7 cummins delete kit, you really need to verify your local laws. If you live in a place along with strict smog tests, you will probably find yourself having to bolt most that heavy products back on every year just to obtain your registration sticker. It's an enormous discomfort, so definitely perform your homework first.
Maintenance After the Delete
Once the kit is on, your own maintenance routine changes a little little bit. The biggest thing you'll notice that the oil stays clear much longer. Upon a stock 6. 7, the essential oil turns jet black almost immediately mainly because of the soot being recirculated. Right after a delete, the oil stays ruby for a large number of mls.
You should still stick to your regular oil change intervals, but you can rest easy knowing that your own engine isn't "eating its own soot" anymore. You also won't have to worry about cleansing the turbo's slipping nozzle, which utilized to get gummed plan carbon on the stock setup.
Is It Worth It?
All in all, it comes lower to how you use your truck. In the event that you're using your own 2007 Ram for heavy towing plus long highway hauls, the stock system could actually behave alone for a while. But when you're using it as a daily car owner or a work truck that spends a lot of time at nonproductive, a delete kit is almost a requirement to keep it from the shop.
The 6. 7 Cummins is a good incredible engine—it's obtained a solid wedge, a great head design, and it can make enormous torque. It had been just unfortunate that it was the "guinea pig" with regard to early emissions technologies. By installing the 2007 6. seven cummins delete kit, you're essentially letting the engine run the way it was designed to run. You get good luck, better fuel economy, and the tranquility of mind that you simply won't get the "DPF Full" warning while you're 500 miles from house with a trailer behind you. Remember to keep your own old parts in the corner associated with the garage—you never ever know once you might need them.
