BIG exhaust problems!!!!

..ok i have a 96 cavalier-but it has a 2.2 liter sunfire engine from 99-im ordering a cat back exhaust-and i have no idea whether to order it for the 96 body or the 99 motor-should i buy one that fits a 2.2 liter 96 cavalier-or one that fits a 2.2 99 sunfire?...seriously i need help-mufflers loose and bubbly so i want a new one soon-and im not sure which one to order-thanks

for the body not the motor.
