Sounds like he blew a fuse or damage the o2 sensor wiring doing the downpipe install.

So you're saying there's no feature in the JB4 to remove the CEL when running a catless DP? Or is that a separate option? Because I've read a lot of posts indicating that the JB products can quash the Catless DP CEL. Just asking.

This has nothing to do with the JB4. Through trouble shooting with Terry at Burger and Crypto I believe we have it nailed down to a connection at the DME. I believe the company that installed the downpipe may have pulled on the o2 sensor harness to get slack for the connection on the post Catt 02 sensor and it may have caused a ground/wiring to come loose at the DME connection. The JB4 had been great for reading the code to help diagnosis.
The JB4 clears the codes when activated as that is one of the features of the JB4 with no issues. These particular codes are just not able to clear as they are constant.
Originally when I posted the codes I was not sure what was causing it.
I will keep everyone aware of the solution.
