Anti Reversion 'doodats' aren't PWTBs freebeard. They're MUCH smaller.
ie: You're not trying to turn exhaust pulses into nice smooth flow;
You're trying to disrupt backward flow in the headers some with the cheapest interpretation of a Tesla valve possible.
They typically go in the branch pretty close to the head, where the pipes get hottest apparently..
