Question about O2 sims and extenstions I searched this briefly but didn't find exactly what I was looking for. I just want to make sure I understand this before I spend the money. So here goes:
I have a 1999 Camaro LS1. If I get off road headers and off road Y-pipe, I assume I need two O2 sims. Do I need an O2 extension also? If so, what length will I need?
If I also replace the rear with a Magnaflow cat-back, do I then need two additional O2 sims and extension for the rear as well? If so, what length will I need?
I really appreciate your help, so thank you very much in advance!

You don't need any O2 sims or extensions for the catback.
all LT headers (assuming you're getting them) are technically off road - you will throw codes for using race only headers because you will be removing the AIR & EGR. since you are going to be staring at your SES light, you might as well skip the O2 sims for the rears (they only prevent a code being thrown for not having the rear O2's plugged in). you will need to use either extensions or vette REAR O2's for the front O2 sensors on your car
For the fronts you will need either extensions, or a set of vette rear o2s (bosch 13111) the vette rears have longer wires and eliminate the need for extensions.
For the rear o2s, you either need a pair of o2 sims, or to have them tuned out.
If you plan on using a catback (no matter what brand) just installing a catback does not mean you have to do anything with the o2 sensors
