Make sure you run the EU2 tune or an equivalent that remaps the car for catless operation, and it will really cut down on that stink. If you just remove the cats without tuning, the car will run pig rich (constant catalytic efficiency testing) all the time and your MPG's will suffer, too.

Would love to. Haven't gotten around to it yet!
