Yeh, just checked technical regulations 5.6 states max of 2 exhaust exits. Although I'm still curious if there is a way of working around that.
Ok, potential workaround, bear with me...
The first, main exhaust, enters through the centre of the back of the car, and feeds the diffuser for all the time the driver is on the throttle. When off-throttle, the engines still fire 4 cylinder currently for the off-throttle blowing. Using a special engine mapping, could the process of cutting to 4 cylinders reroute the exhaust gases through a second exhaust to aim at a rear tyre. Again with the engine mappping, could the 4 cylinders used alternate by corner, and when using the second set of cylinders, the exhaust gases be routed through a third exhaust, aimed at the other wheel. Technically at no point are all 3 exhausts simultaneously, and something has to move inside the engine to stop fuel injection to 4 cylinders anyway, so why not combine this with shutting off the exhaust port?
Or am I both displaying a limited knowledge of the rules and trying to bend them too far?
