Hi!
I'm new to the forum and to the 6.7 Powerstroke.
I'm wondering if there's any way to upgrade the muffler or possibly going with a straight pipe after the CAT and DPF without getting codes?
What are the plus' and minus'?

I have a MBRP True Duals basically a straight pipe no codes and just bolt on.

You are not going to get any extra sound until you delete the DPF. The DPF is what makes the truck near silent. Adding any Post DPF exhaust is only for one thing, appearance.
