Roush California Saleen's

I am considering purchasing a one owner 02 Saleen S281-SC from California and was wondering what kind of additional smog equipment if any it came with it? I live in Washington and was curious to see if it was possible to remove it if it choked the engine or hp at all. Thanks
 
There is no difference from the cars sold here in California and in Washington State. So go ahead and cut away. These cars like a true x-pipe and a Bassani stainless exhaust with headers. Don't bother with the long tubes though.
