I consider myself a "closet-environmentalist" which means I don't go nuts but when I have the opportunity try not to pollute, so I'm not willing to run it w/o a cat or O2 sensor. Knoepfler has me taken care of on the down-pipe and cat, so now I just need a cat-back setup for an M42.
I'm going to stuff the 535i in a garage in fuss with it later.
