View Full Version : LT headers and 02 sensors

11-10-2011, 06:08 PM
If I get LT headers will the oem pre-cat 02 sensors work? Do only the post-cat 02 sensors need to be extended? I have heard of the longer corvette ones working for the post-cat and am assuming the pre-cat 02's do not need to be extended.

longtubes will move both 02's futher away. You will need extensions, or longer o2's. Alot of us delete the back 2 so only have to mess with the front 2

You will need to delete the rear o2s and buy extensions for the front. Feel free to give us a call if you have any other questions.

there is a thread about rewiring your O2 sensors so that you can use the Rear O2 sensors as if theyre fronts.
