Can somebody please tell me where rear 02 sensors should be located? I have the pigtails I just want to weld them where they should go. Someone has put bigger exhaust and high flow converters on my car. Thanks in advance for any advice.
Rear o2's go after the cats. Since they have heaters to get them to operating temps, Id say anywhere from 3-6 inches past the cats.
But, why don't you go to 4th gen section, in the sticky threads, you'll find the 4th gen parts books for download. The firebird part book should have a diagram of exhaust system. It will show you exactly where factory put the rear o2's
