Does a 2005 ford F-250 need a catalytic converter or can you cut your 4in turbo back exhaust short and have it exit in front of the rear tire?

If it came from the factory with a cat it is aganst federal law to remove it... also if it has o2 sensors before and after the cat it will affect running of the truck...
