Need a cat? The lack of one will not affect the way your car runs, only what comes out of the tailpipe. The VX cat is very close to the cylinder head so it can stay as hot as possible when in lean burn.
I would keep my eyes open for an opportunity to maybe pcik up some used parts from a modder who did not want the weak lean burn engine in his civic. Probably not worth spending a lot of money to make an old car like new, but the oxygen sensor is critical.
