Yes and no. So when deletes are done, it is as simple as when we did with cats. Just drill it or chisel it’ out. What’s not so simple is the ecm and calibration side. It won’t only be the pressure sensor but also temp since the doc won’t be there to create the heat it needs. The simplest way to do it to find an ecm code from overseas for the same base engine but no emissions or I had a guy in Miami that had software to actually rewrite the factory calibration and remove the emissions stuff and let me tell you deletes make a ton of money. We did full deletes including EGR. $5-7k (in about 3-4hrs)depending on the customerWe were debating that idea a couple days ago. Can you punch a hole all the way through a DPM muffler and make it run without triggering a differential pressure sensor code? The problem right now is getting parts. DEF senders and DPF mufflers are backordered to who knows when. We have 8 machines down right now and counting.
We are on the same boat with the DEF headers, we currently have 13 truck on the lot waiting. They are on a national backorder.
