Angry It's Cherry Red HELP!

Where the 3 pipes come off the block to the 1 Is glowing cherry red only on the drivers side it occurs after about 15 min of driving and causes smoke to enter the drivers side. It's severely bogging down the "performance" of the car giving me about a 0 - 60 in 2 - 3 min. I might be exagerating a bit but it is realllllly slow.

No the motor is not overheating, no water or coolant in the oil everything looks normal. It is the 2.8 RS Automatic '89. Exhaust sounds like there is a leak, like a hissing sound. When I was on the gas it sounded as if it was working too hard.

That's what me and my husband were leaning towards however would that only cause one HEADER to be glowing red. Because I assumed that both would be glowing, and there is exhaust passing through although minimal.\

dual exhaust? strange that only one is doing it. if not duel does it have a floppeer valve on crossover pipe on the exhaust.

not sure about an 89 but the old style motors used to have a valve that evens up the back pressure, they used to get stuck on us. i would guess that if it has a crossover like my 93 (does not have a flpr valve) and it crosses from the drivers side to the passanger side that the closest manifold to the cat would get the air flow.

It has a collector off of the headers before the catalytic conv., then runs back to a transverse muffler with two exhaust pipes. Being that it is a V6 the side that is glowing is the side that has a direct line to the converter. The ceramic gaskets between the actual headers and the downtube was cracked on one side but the side that was glowing was not.

could be that leak or crack let just enough air out to not get red.

Ok So then the next question is since this exhaust system seems to have been modified does anyone have a pic of the original exhaust system or a diagram.
