Its gonna stink without cats but that doesn't mean its running rich. Aside from maybe puffing some smoke and fouling out plugs running rich shouldn't hurt anything too much except overall performance.
I assume your car has been tuned by a competent tuner? If so, it shouldn't be running too rich.

It has been dyno tuned. AFR was at 12.5 and ever since the Fast install, it seems a bit more smelly and I've noticed my gas mileage has gone down slightly. Don't notice any real power loss. Seems to pull pretty good. I might take it back to the tuner and see what he thinks. Thanks guys.

Its already been said, but you can definitely kill an engine running it too rich.
One thing that hasn't been mentioned, as a result of washing down the cylinder walls, excessive fuel gets into your oil...
Lets just put it this way, fuel sucks as a lubricant, and you can easily toast a bearing in the engine.

Yup, no cats will cause the exhaust to smell. One thing I haven't seen mentioned though is that generally the smell is pretty similar when the car is running rich as to when it is running lean. So maybe the addition of the fast may have leaned the car out somewhat.
