Default Dummy O2 sensor???

Hey there, im bout to get a 99 ranger with a 3.0 and im gonna put exhaust on it. ive read that these trucks have 2 cats from the factory. Right now my plan is to cut both of the cats out and weld in a hi flow cat and have a y-pipe straight with dual 3.5" tips. I have read that by doing this i would throw codes left and right. so i was wondering if i put a dummy O2 sensor would it stop throwing codes??? Thanks for the help yall

Your 3.0 Ranger came from the factory with 4 or 5 cats, all of them high flow. I'd leave the cats alone and put the money toward a quality cat back system.

go 40 series Flowmaster single in dual out, you can add 3"-4" tips to deepend the sound, deeper the better...... dnt hack up the cats you'll hate the sound. it will sound awful.

as for sensors:
you can unplug 02 sensor, will increase horse power, but will cause cat failure/clog n will not pass emissions ..

If your good with soldering and such you can make a dummy o2 sensor with some resistors the thing is how fast they will burn out etc plus you have to know the correct resitance the 02 is putting out for a clean burn. Read more hastle then you want to deal with if you want to chop the cats do it run a full straight pipe put on a Flowmaster 10 series muffler they have a good growl. In the end though its all up to you.
