Ok,

I talked to a greddy tech and he said that they should come with the part welded (to insert the O2 sensor) on... I talked to the place that sold me the part they said that it doesnt, (the guy i talked to said his friend had a 96 accord same engine as mine and it didnt come with the welded part for O2 sensor) so anyway I am going to just move the O2 sensor down right after the downpipe and put it on a aftermarket catalytic converter
