I'll do an undertray at some point. But... are those resonators or catalytic converters on the exhaust pipes just aft of the engine bay? With grills blocked and the belly enclosed, I would think heat builds up more, especially if the CAT is still in the bay, no? These cars have more cooling capacity in some other way? Better pump or radiator?
