I have had my 2020 Duramax for 3months now (October 2019-January 2020) and no one has came out with a DPF back exhaust kit so I came up with my own solution. I used a 2017-2019+ exhaust turn down tip with a 5" - 6" MBRP exhaust tip to create my own look to the exhaust and get rid of the ugly horn in the back. Below is a parts list:

PLEASE TAKE THIS PART NUMBER: FLOPRO ST11070B and insert in a google search a lot of places are out of stock. Took me about 20min to find a place that had it in stock.
