Angry Help! engine starts and dies

I just installed Pacesetter headers and Y-pipe and the engine starts up roughly (like a cam) and dies unless I give it throttle. could it be loose/broken sparkplugs ? or maybe the O2 sensors ?

Double check all your spark plugs and wires? Make sure your o2 sensors are plugged in?

You broke, disconnected or reconnected something incorrectly. Go over everything.

does it run fine until it warms up then die? you might of crossed the o2 sensor connectors, which will cause it to add fuel to wrong bank and remove fuel from the other bank,
