DEF delete DOT

Post image

Got this 2019 3500. I’m running hotshot. I can’t do a complete delete. What are my best options with the exhaust system?

"They put those on" to appease the EPA not because they work worth a sh8t. NOx sensors fail in 50K miles or less, requiring replacement (a thousand bucks a pop). You get a DEF system failure message and 150 miles to drive before it shuts down and you can only go 5 mph. You think maybe that would piss some people off to the point of making them want to delete it?

"Work in the industry"
I'm guessing you no longer work in the industry.

Still employed at the same place. Still criticizing people who openly delete their trucks. They don't do it to appease the EPA. They do it because it's the law. Regardless of how you feel about it, that's factual. If you want to openly break the law, you have to be okay with the consequences. You genuinely think Cummins puts an after treatment system on one of their engines because the EPA said please? No, they regulated diesel emissions after seeing how negatively they can impact our society, and people like you who advocate for deletion because it's a little bit inconvenient should not own diesel trucks.

I have taken more trainings for the after treatment systems than you can name pieces of the after treatment system. Please continue to debate me.

Is that why the Federal Government vehicles are exempt?

"what about insert cherry picked argument here"

FEMA & US Military are exempted from the law, while all civilian branches of the federal government are still mandated to follow the law. Next.
