If you are running a CAT on a 95 you should have a lambda sensor in the collector at the bottom of the down pipe, visible from under the car, at the front, inward of the front wheel.
What you have at or after the CAT is a CAT on fire sensor which will be redundant with the 3" open neck D/P.
Remove the sensor from your collector and pull back the harness sufficient to locate the sensor in your new down pipe. Blank the threaded hole in the collector.

Thanks for the help will give it a try but it will be ok to remove the cat on fire sensor & relocate the Lambda?
