I dunno about the SN95 mustangs but the fox bodies have two cats per pipe.. and the O2 sensor is BEFORE the cats.. so removing the cats wont mess up the computer... as for HP gains... theoreticaly you should gain some... but what you gain the most is volume.. though I like the sound... so it's cool for me... I know some later model cars have O2 sensors after the cats.. but I dont think they do in your car..not posative about that though.. just look under there....
any new OFF ROAD H pipe will come with the nuts welded on so install the O2 sensors.. you need those regardless of cats or not
