Duramax LML EGR Delete Kit

Should you perform an EGR delete? Is deleting Duramax LML EGR a simple procedure?

On my 2011 LML Duramax, I was thinking about doing an EGR delete. The truth is that it is extremely inconvenient and time-consuming. But all I wanted to do was extend engine life and increase mpg. Given how difficult it was to remove and reinstall all of the engine mount pieces, I can’t imagine doing the EGR delete. I live in Aberdeen, South Dakota, where it frequently freezes. I couldn’t decide whether to buy a new up pipe or install the sinister LML EGR delete kit. So I followed the advice of the experts. I’ve included the expert’s responses below-

Philip- “Eager to finish my delete procedure, I wondered why I hadn’t done so earlier.” I’m not sure whether I should wait longer to gain more time or if I should hurry. I stopped after 40K feet because it wasn’t optimal for the few kilometers I walked. It wasn’t difficult to get rid of the previous pieces. The most difficult part for me was removing the previous downpipes from above. Instead of simply capping the stocks, I went with Profab’s up pipes. If you do the full delete, I highly recommend the Profab EGR delete tube. The delete tube and up pipe were excellent.”

Jimmy- Make a full delete, not just the top of the bell (blocker plate). The most difficult part of the cleanup is unscrewing the bolts that hold the bell in place, so if you have the chance to loosen them, do so. It also appears to be clean. With 175,000 miles on it, this is my EGR and cooler. It’s simply stupid to put it in your engine. I’ve seen much worse sights with only 3-4 hours of work.

Jack- Without a doubt, the best parts come from the Deviant race parts. It costs $450 to purchase the entire kit, which includes the new stronger up-pipe. It is worthwhile not only emotionally, but also financially, if your EGR cooler is leaking externally. The downpipes were the most difficult to install. Fortunately, I completed both tasks. By the evening, the EGR cooler had been replaced. It took nearly an hour to remove the EGR.

Duramax 6.6L LML EGR DELETE by Deviant (2011-2015)

Because everything I needed was included, I chose to buy on-demand up pipe gaskets that were not included in my deal. Deviant Race Parts manufactures their parts in-house in the United States. It was by far the best option that I had. If you’re not willing to spend at least $1,000 on manifolds and up pipes, Deviant’s LML EGR delete kit is a no-brainer. Whereas a quality LB7 pipe costs $300 and a thick blocker costs $100, Deviant will charge nearly $455 for a generalized setup as well as a couple of hours of labor behind the scenes.

I chose the Sinister with the reliable cap plate. It’s been up for over two years with no problems, and the crack up-pipe is a complete myth; that’s all there is to it. Fortunately, it’s only caused by people pushing the more expensive option.

Knowing that mine might crack, I’d take an LB7 up-pipe along with the Sinister deletes to recharge the grid heater.

If you get the Sinister, only replace the EGR gasket; don’t ask to use the old one. Furthermore, there will be less work involved, and the installation will be relatively simple.
Other EGR delete kits that require an up-pipe or rebuilding an additional portion of the engine look nicer. If you abandon the stock grid heater that you keep with the Sinister.

If the grid heater is required, it must be purchased in addition to the other EGR. It is more expensive for you. Yes, if you’ve removed the EGR, the grid heater will lengthen the processing time.
