You bring up another interesting device. An anti-reversion device. The perfect place to put one is at the point where the exhaust pipe is stepped up, when using stepped primaries. That brings up another topic of discussion. Continuously tapered exhaust primaries. Yes, I have actually seen them. Very, very expensive. Stepped primaries are nothing more than an inexpensive way to simulate a tapered pipe.
