Delete EGR but keep the DPF
Is it possible to delete the EGR but keep the DPF intact? I have a 2012 and really like the clean exhaustbut would like to get rid of the EGR.

No, the egr is what keeps the DPF from plugging up.

It's all or nothing when deleting...

You can leave the upper cat in-place, and possibly the lower one (never heard of anyone doing that, but I don't see why not).
But keeping the DPF while ditching the EGR is like breathing cleaner air, but still having a bad case of constipation. |

I have to agree. The newer trucks with Def have a reduced EGR cycle but their DPF doesn't plug up, it actually regens less. The def reduces NOX, not soot.

I don't believe that cooled EGR will cause the DPF to plug. It's job is to lower combustion temperatures and this retards the formation of NOX. In theory you should have a cleaner burn with more abundant O2. The DPF is designed to reduce the amount of soot that comes from burning diesel fuel.
