2012 LML DPF Delete

If I delete the DPF will the soot be visible and let the cat out of the bag?

The cat will be out of the bag because the computer will register it. My concern would be the DPF plugging up with soot.

Yes the soot will be visible, and yes the warranty will be done because the delete will require programming changes.

Thanks for the info, guys. I'm gonna go after a Mini Maxx, but skip the $100 unlock code and leave the emissions be.

Afraid I'll wind up in the CrowBar Hotel, or at the very least get a hefty fine. I'd like to ditch the DPF because it dips to -45 up here in winter and with DEF being 75% water ( and 8 bucks a gallon) I'm worried about freeze ups. Probably get better mileage without the DPF too.

Yeah, if your going in, might as well go all in. Delete the dpf and def, and get a good aftermarket exhaust. If you don't, you'll choke out the motor because the dpf will get clogged, without any regens.

All in it is. Any mileage to be gained by getting rid of the DPF/DEF setup? _________________________________ 2012 Chevy 3500 LTZ Z71 CC/SB Black on Black

Delete if you like, but the system is supposed to be able to deal with artic conditions. Perhaps some using LML's in the far north will chime in.
