Shorty belt & precats

[daz95gt]

Does shorty belt which disables the smog pump also disable power steering or something else?

Does the cats need those precats to get their work done if the engine is warm already or does the precats only get cats heated quicker?

There is emissions test once a year during vehicle inspection here in Finland and I thought that changing a shorty belt for a stock one once a year wouldn't be big job for extra power. However, if the short belt also disables power streering that won't rock. I'm also worried because of that emissions test if i'd get rid of those cats. Would I pass those tests still without precats? Would there be any increase of exhaust flow w/o precats?
