DPF Delete Kits
1. Maximize Diesel Performance with SPELAB Straight Pipe & DPF Delete Kits
For diesel truck owners seeking more power, efficiency, and durability, SPELAB offers the ultimate upgrade: DPF delete kits and straight pipe exhaust systems. Whether you drive a Powerstroke, Duramax, or Cummins, our precision-engineered solutions reduce backpressure and exhaust temperatures (EGTs) while improving throttle response and fuel economy. Built from T304 stainless steel, our systems are designed to deliver freedom, reliability, and aggressive diesel performance.
2. What Is a Straight Pipe & DPF Delete System?
In diesel performance upgrades, Straight Pipe and DPF Delete are often discussed together. The former focuses on optimizing exhaust flow, while the latter removes emissions control devices—together, they form a key strategy for maximizing exhaust efficiency and unleashing engine power in diesel vehicles.
At SPELAB, a straight pipe setup typically includes a DPF delete as part of a full exhaust upgrade system. However, they are not entirely synonymous—DPF delete specifically targets the removal of emissions-related components, whereas a straight pipe aims to create a fully unrestricted exhaust path from the turbocharger to the tailpipe.
A Straight Pipe Exhaust system eliminates the muffler, catalytic converter, and DPF filter, allowing exhaust gases to exit the engine through the shortest, most direct route. This significantly reduces backpressure, improves turbo spool-up, lowers exhaust gas temperatures (EGTs), and increases fuel economy.
On the other hand, a DPF Delete involves physically removing the Diesel Particulate Filter and reprogramming the ECU to disable the DPF regeneration function—resulting in a fully liberated exhaust system.
To better understand why a DPF delete delivers such dramatic performance improvements, it's helpful to first look at the components that make up a factory DPF system:
| Component Name | Function |
|---|---|
| DPF Filter | Captures particulate matter (PM) in exhaust gases to reduce pollution |
| Differential Pressure Sensor | Monitors pressure difference before and after the DPF to detect clogging |
| Temperature Sensors | Monitor exhaust gas temperature to determine if regeneration is needed |
| NOx / O₂ Sensors | Analyze nitrogen oxide or oxygen levels to adjust emissions management |
| ECU (Electronic Control Unit) | Receives sensor data and manages the DPF regeneration cycle |
| Fuel Injection for Regeneration | Injects extra fuel into the exhaust to raise temperatures for soot burnoff |
| DPF Warning Light | Illuminates when DPF is clogged or malfunctioning |
While these factory components are designed to comply with emissions regulations, they can also cause significant drawbacks: restricted exhaust flow, increased fuel consumption, frequent maintenance, and excessive engine temperatures.
With a SPELAB DPF Delete Kit, you can precisely eliminate these components and disable DPF regeneration through ECU tuning—delivering noticeable gains in horsepower, responsiveness, and reliability.
3. What is DPF Delete? How It Works? And DPF Delete / Eliminator Kits Pros & Cons
The diesel particulate filter (DPF) traps soot to meet emissions standards—but often causes exhaust restriction, higher EGTs, and increased fuel consumption. A DPF delete kit from SPELAB replaces the factory filter system with free-flowing delete pipes, enabling your engine to breathe properly and respond faster under load.
Diesel Particulate Filter (DPF) removal involves physically removing the filter from the exhaust system and reprogramming the vehicle's ECU (Engine Control Unit) to disable associated functions. This step is critical to preventing trouble codes, limp modes, and other operational issues. Specialized tools or diesel particulate filter removal kits are used to perform this process and ensure that the system runs smoothly without the diesel particulate filter.

Awesome product I put the 3" cutouts on my 78 nova and they work great. Easy to install.
After installing the Spelab intake my EGT’s have lowered about 150/200 degrees from stock! I tow 90% of the time with this truck, I should have done this upgrade way earlier!
This kit came in a very nice box with all the necessary hardware to complete the installation without any modifications. Installation time was about two hours working methodically by myself with some occasional help from my 13 year old son as he passed through the garage. As many others have commented it would be nice to have some printed instructions with the kit, but it is not hard to figure out. I went with the red version because it was the cheapest, and I think it looks great. After installation, custom tuning with a mm3 tuner, and an upgraded exhaust the 6.7 is opened up and free to run.
Great components solid workmanship very happy with the product and looks really rood. I went with the red
I am a mechanic so it’s hard for me to say someone with absolutely no skills that this is easy. But watch YouTube I will say everyone is worried about the egr exhaust bolts. But one video he sprayed them and soak them. I had sprayed mine each time I drove the truck and every morning for 4 days. Than another video a guy said drive the truck get it hot than when you go to take them out hit the socket and extension with hammer to loosen them. So I also did this. They all came out with absolutely no problem. I did have to take off my intake cause I did the ccv and disaster kit as well. And these bolts did not get sprayed. And one did break! I was able to get it out with wd40 and pb blaster and tapping with hammer. To drop dpf I sprayed the hangers with pb blaster used a pry bar and they pop right off. Remember when taking that off you might miss a coupe connectors so take your time! Also the back of dpf I had two broken studs and one so rusted that I had to use a grinder. After got it out I had to take a drill to my existing manifold cause the rusted bolts closed up the holes. Currently I left my dpf tank in the truck. I plan on removing it but I don’t have a reason yes!
Make sure to read all instructions and again take your time. I’m currently having issues updating the mini max cause I didn’t do it before install. But spe hands down was amazing the products everything was perfect besides the intake. The mass air flow sensor didn’t fit and to clean the metal shavings I used brake clean and it melted there spray paint on that one product, everything else i believe is powder coated. I know it’s not part of this kit but the cp4 disaster kit make sure you tighten hose clamps I did not do this and it cam off so I had to take upper and lower intake off on the side of the road and lucky the truck didn’t burn down. But I would say that was my fault for not verifying!
Fits great! Easy install! All parts come with this as well didn’t need to go out and get anything. Not only that but the price man that’s damn good
Good fitment on all items. All block off plates fit good and dont leak. Downpipe fits perfectly. All gaskets included good quality.
I’m so happy with my egr delete kit and intake. I made the best decision in choosing Spelab to enhance my 2500 ram truck. I’ll keep buying more stuff from them. It’s starting to be an addiction!! Thanks Spelab!!
The exhaust and muffler fit great. Had to make one cut but that took no more than a couple minutes to measure and make the cut. I’m very pleased with the muffler included, sounds good but keeps the noise down and no drone in the cab. Will buy again.
Everything fit great. The finish is good and it includes everything you need to get rid of that POs Egr cooler
You know how it goes when you try to save a dollar, you cut cost of quality. But this is actually not the case so far. Finish is smooth, no bad cuts that i could see. Plate wasn’t warped with was a concern for me but no leaks this far. I’d buy again
Love the pipe however one band clamp was damaged upon arrival. I was able to bend it back to the correct form and use it. All hangers were in the correct location took about 30 mins for me to install by myself.
Intake came in nice and shiny looks like a great product also got the red intake plate and man oh man does it look sharp, overall I recommend Spelab products. Looks clean performs even better
Comes quickly in a little box. I work on my truck but am no mechanic. It took me 2 hours to remove and install the kit. Im very happy with the outcome. Im going to give it 5 starts but you do have to reuse the two gaskets on the EGR cooler. My advice is pick them up from the parts store so its all new. Total cost is $24 for both. They should be included but im still very happy.
Great product. Does everything it is supposed to do. I do wish it came with printed instructions. Following along with greasy fingers on my phone was problematic. Also, the hose fitting for the coolant line was a size too small. I had to purchase the correct size.
