2012 Silverado 2500HD with 125K. I've been changing DEF and emission parts as they die this last month (around 1,500$ so far), but now the cat has an internal crack and I'm looking at a 2000$ part and two weeks to get it in with the GM delay. Thoughts on just deleting the truck since I'm in a state that doesn't regulate diesels and I'm well out of warranty? If moving forward with the delete, suggestions for the software and after market cat are appreciated. This is a work truck and daily driver. Thanks for any information provided. Any questions or if this is the wrong area for my topic, please let me know.
