Caterham and Williams drop contested exhausts

Given that the FIA declared Caterham's exhaust vane and Williams' exhaust bridge illegal, both teams have opted to back out of the option and not risk being disqualified at the Australian GP, the first race of the season where cars will be fully checked on their compliance with the technical regulations. Both teams simple bolted different parts on their cars, knowing that for both the CT03 as well as the FW35 the contested items were easily removable.

The image clearly shows the lack of vane on the Caterham, while also showing burning marks on the car's bodywork due to the internal components heating up the carbon fibre and its paint.
