It's a balancing act between HC and NOx and I'm not sure you can do it without cats. If you lock the car in open loop and lean it out, HC will drop. However that causes combustion temps to rise and thus NOx wil rise as well.
All cams have an overlap period between the intake and the exhaust valves while both are open. Therefore no matter how perfect your combustion is, you will always been getting some HC's right from the intake out the exhaust.

The slick route is with the SLP system. They come with removable cats. All you do is install the supplied straight pipe after the sniff test. Really slick is adding the cut outs to the straight pipe.
