Definately not, those would be massive for wastegate pipes. 2000bhp single turbo drag cars have smaller wastegate exits. Not to mention no one's going to have screamer pipes in a street car if they want any chance of passing emissions. In pictures where the car has the twin exhausts exiting the diffuser it doesn't have the quad exit. But in those pictures from South Africa you can see the exhaust is definately routed to the quad exit and apparently they're just using the old diffuser which had holes for the test exhausts.
