Removing the intake manifold, EGR valve, and cooler, then installing block-off plates and rerouting coolant lines, can lead to serious issues like leaks or poor engine performance. But the payoff is worth it, especially if you own a 6.6L Duramax LLY.

What is the Dynovox EGR Delete Kit for 6.6L Duramax LLY?
The EGR Delete Kit from Dynovox is an affordable take on 6.6L Duramax LLY. Each order includes everything you’d need for the install, and everything lines up how it should.
The EGR Delete Kit comes with high-quality block-off plates to seal the EGR ports, a high-flow intake to replace the restrictive factory EGR cooler, and all the necessary hardware for installation. The high-flow intake is particularly good, as it provides a much more fluid airflow into the engine, resulting in a boost in engine power as well as efficiency.
How easy is the Dynovox EGR Delete Kit for 6.6L Duramax LLY to install?
Installation was truly frustration-free. Dynovox is purposely marketing its kits to DIYers, and as such, it recognizes that many of its customers are first-time tinkerers. That said, installation instructions provided by Dynovox are crystal clear and clearly illustrated.
Ultimately, the whole delete should only take about 2-2.5 hours. (Just take your time and don’t get frustrated with the nuts in the back. A deep well and a short extension with a flex head should get the job done.) However, if this is your first EGR delete DIY session, budget in about 4 hours all told. On the upside, there is no need to drain the coolant.
Is the Dynovox EGR Delete Kit for 6.6L Duramax LLY worth the money?
Answering the “Is the product worth the money?” question isn’t always easy. You have to balance the cost of the product versus its competitors, how easy it is to install and use, the performance gains, and how often someone would typically use it. In the case of the Dynovox EGR Delete Kit, the answer to all of these questions is a resounding “YES!”
Compared to the price of other EGR Delete Kits on the market with similar capabilities, the Dynovox EGR Delete Kit is far more affordable. Secondly, the kit is incredibly easy to install and use. Finally, paying someone to delete a 6.6L Duramax LLY isn’t cheap, so using a DIY kit is definitely the way to go. Especially if you want more power and fewer fill-ups at the pump.
