---tab Description---
A complete 3″ Turbo-Back DPF delete exhaust system for 2016‑2019 LWN 2.8L Duramax engines. Made of durable 409 stainless steel, it replaces the factory catalytic converter, DPF, and tail section to reduce backpressure, improve turbo response, and deliver a deeper diesel sound. Ideal for off‑road, performance, and heavy‑duty use.
Key Features
- Complete Turbo-Back System: Provides a one-piece, integrated solution replacing the downpipe, mid-pipe, and all necessary hangers/hardware—no welding or custom fabrication required.
- Muffler Delete Design: Eliminates the muffler for maximum exhaust flow and a more direct, powerful, and deeper diesel sound characteristic.
- Performance & Durability: The 3-inch diameter 409 stainless steel construction reduces backpressure, lessens strain on the turbo and engine, allows for easier torque release, and offers superior corrosion resistance compared to factory piping.
- Direct Bolt-On Installation: Designed to utilize factory mounting points for a straightforward installation process.
- Optimized for Tuning: Works ideally with ECU-tuned or modified vehicles to maximize performance gains.
- Suitable for Demanding Use: Recommended for off-road, towing, racing, and non-highway environments (e.g., farms, construction sites) where durability and performance are critical.
Specification
- 3" Back Exhaust system.
- T409 Stainless Steel
- Single Side Exit
- Easy Installation - Mounts to OE Hangers
Installation
- Estimated install time: ~1 hour with basic tools; faster on a lift.

Purchased a ccv reroute kit. It was easy to install, fits well, quality parts. I plan on using this company for my EGR delete also. The power stroke kit comes with everything needed. I highly recommend.
Ccv reroute for the l5p needs revision but absolutely will work good parts
Very nice features and great quality at a very reasonable price!
Very well made product
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
