Anyone removed the DEF system?

[Ed Hryciuk]

Has anyone removed their DEF system? I have heard that you get better mileage and power. Of course, I'm not sure about the legalities of that in your area.....

I'm sure the warranty is NUL if you do remove it.....

I want to remove mine, but the 1,800-2,100 price tag

DEF cannot affect mileage or power. The SCR is at the end of the exhaust system. All DEF does is neutralize the leftover NOx emissions. It is totally unrelated to the engine. You gain nothing by removing it

You gain more smiles per gallon.
