I just don't see that working. There is so little catalytic material in there it's not going to do anything. Might as well just drill a smaller hole so less exhaust gets in there.
O2 spacers work on some cars and not on others. I'm going to go out on a limb and say that the people that say the mini cat works are the ones who could have just used regular O2 spacers. The BMW is very, very sensitive and O2 spacers don't work. I've tried several, we used different lengths and hole diameters, nothing works. But on my Infiniti, they work great.
So $70+ shipping for mini cat which is basically $5 in O2 spacer + a few $$ in "catalytic" material. If they ever come out with a DP Fix for the N55, get that.
