02 sims? for hedders. i am about to get some pacesetter headers for my 02 trans am.besides the hedders an y pipe, do you guys thing i gotta get new 02 sims an new 02 extensions too. do you think my olds ones will still be good?i would greatly appreciate any help.
If you already have the sims and extensions then no they will be fine. If you do not have them yet then for about the same price you can have the proper O2 sensors turned off in the computer from a tuner or just find a used set of sims in the classified section. Texas speed I know sell the extentions.
If you wind up needing new O2s, get Bosch PN 13111. They have a longer harness and don't require extensions. As far as sims, just deal with the light until you get a real tune, unless you already bought them or just don't plan to ever do any other mods, and if that's the case, you better not browse this site anymore, cause reading about this stuff is contagious.

If the car is all original you will have to get extensions for the top two sensors. With 56K on them it wouldn't hurt to pick up the Bosch O2's because the extensions will be half the price of the new sensors anyway.
Don't spend the money on Sims. They aren't needed for engine management. Just plug the rear sensor bungs and have a shop turn off the CEL.

Rear O2's will run cooler with headers and may not work correctly. The Bosch 13111 has higher power heaters in them and will compansate for this. They also have longer cables eliminating the need for extensions.
If you tune them out, you may have a problem passing inspection because the system looks for signals from all the sensors.
