Not making power any more...

Unsure if you’re throwing any codes; but I know using impact wrenches on exhaust could damage O2 sensors, also if you have an exhaust leak in that area...would cause issues.

In theory, wouldn't test pipes feel like an exhaust leak to a system tuned on 93 with cats having them now removed?

No codes, no impact tools, I am always super careful with o2 sensors at $200+ each. I used only a crescent wrench to tighten them after hand threading them.
