Need some input from those who know...

09 GT 500 5.4. Headers, no cats. Tuned for no cats. Can one unplug the rear .02 Sensors and not expect any issues (throwing code, etc...)?

Can give more details if necessary.

TIA,

David

Probably wont pass inspection.

More concerned about running rich right now.

If it was tuned for no cats, the tuner most likely has down streams turned off via sct. If this is the case, unplugging will make no change

Thank you sir. That's what I thought. Just wanted to make sure.

No problem sir

Doesn't explain why you have front sensors after the cats and rear sensors before the cats.

Can't figure out how the connectors were switched, especially when I couldn't get the front wires back to the rear where they apparently belong. But there's no doubt that they were switched at some point! Also, couldn't have been Bryan because he never touched the wires other than to plug in what I gave him, which is what fit in that connector.

I've got 'em switched now and after I get the tires back on, I'll see what happens. Started it and "appears" to be running better, but will have to wait and see.
