O2 Deletes

Can any body give me a web address were I can find these things, Im putting long tubes and a y pipe on my 99 Z and need to get a pair of these for the rear O2s. Ive been told they dont sell them anymore, help me out if yall can, Thanks

just get headers that are compatible with o2 sensors.
really, you want them in there.
otherwise your car will loose about 10 hp, your gas mileage will be worse, and you will have a hard time getting it to run right
