6.6L with DEF


Recommended Posts

So I want to add a little more sound to my truck but unlike most diesel owners I don't want to roll coal.

 

Can I just do a muffler delete with out harming any of the def system?

 

Has anyone done this?

I know you can get DEF back exhaust systems.. Not sure where. Check out duramaxforum.com. You'll get a lot more info about your dmax there. 95 percent of the people here have halftons
