In need of some guidance

I forgot. The L5P has the SCR after the DPF that would just clog up if you flipped the DPF around. Can still pull the DPF and wash it though

Scr won’t plug up but it’s possible it may cause issues with it working properly and sending either reductant quality codes or other codes.

The SCR is actually up next to the transmission. I think they have another DOC element in the can with the DPF though.

 

[Chevy1925]

Yup, damn I completely forgot they flipped the scr and dpf. Too many dodges in my life lately .

So flipping the DPF is back on the menu?

No becuase the small doc will be on the wrong side. It does have one of those

Did they combine them in that year?

Kinda. So there is a large DOC right at the back of the turbo, then the SCR, then the short doc with the dpf right after it (it looks like one big unit)

I remember the one that is bolted right to the back of the turbo, so the 2nd DOC and DPF are inside the same housing and thus can't be reversed. I'm liking the simplicity of LMM even more now

Yup and I agree lol. Rarely does a LMM show up with an aftertreatment problem
