I assume you're joking since that would likely destroy the effectiveness of the GenTuri. The exhaust pressure drops pretty low when the hot gas expands from the smaller exhaust pipe to the larger plastic riser tube. The exhaust heat causes the exhaust/air mixture to travel up the tube with minimal pressure. The cap would likely just cause most of the hot exhaust to exit at the open bottom of the larger tube.
