Guess:

This is likely over-fueling and combustion isn't finished in the cylinders. Causes include excessive fuel delivery for assorted reasons and timing wrong including valve timing. You may need some help to diagnose this out and I wouldn't wait as it will kill the converters if neglected. Timing belt or chains at the miles need be known correct and on the mark,

If the exhaust manifold glows red it could be a cloged converter. Usually It will lose power on hills. If not then an oxygen sensor will also cause it to get extremely hot.
