The exhaust was being used to deflect the rear tire wake away from the diffuser, to increase its efficiency, OR re-energize the flow at the back of the diffuser. The downside, was the on/off effect based on the engine rpm, engine mapping, or throttle control entering the corner was key, to keep from upsetting the aero balance.
Way more complicated, than what anyone would get to work on a street car.
