My exhaust header developed a bad crack and flooded engine bay with hot exhaust gasses. I have rewired all injectors and sensors on engine however I am noticeing a loss of power once engine has run for 1 min or so. I think my baffles in the muffler have shook loses (serious rattle while engine running or even with a good kick).

Could the problem be back pressure in exhaust system not allowing clyinders to clear on exhaust stroke?

I am having a new exhasut system from header to tip installed tomorrow. I just want any other ideas so I can tackle them while I have the jeep torn open.

I don't think that's baffles you're describing. That's more-than-likely carbon buildup that occurs in everyone's muffler after years of use. The carbon hardens into balls that bang around inside the chambers of the muffler or catalytic convertor if they've become dislodged inside from the muffler walls, i.e. the expulsion of the gasses you've just described, a direct hit to the muffler when trailing, etc..., which is why it's making all this racket now.

Ohh, and loss of power can come from loss of proper compression due to a clogged muffler, where of course the carbon buildup is. So clearing out the muffler and cat will improve airflow out the back, hence giving you better engine performance.
