It may pass the sniff test but not the visual.
You are not allowed to remove or replace any emmisions device unless it has been found to be deffective or after 100k miles I think.
The reason the cat is so close to the turbo is for cold start emissions reasons.
They need the cat as close as possible to the heat source(the engine) in order to "light off" the cat or bring the cat con to operating tempretures.
When cold the cat con doesnt do much at all.
This is the reason WRX's have a cat between the engine and the turbo.
The turbo is a great 'sucker' of heat and energy.
Good luck,
