Lynn,
Another thought.............What do you think an "Extractor" system (In my "Delta's" case
one on each side of the bottom "V") consisting of large diameter tubes (5-6" ?) exiting
behind the cockpit with 2" tubes down the middle and open to forward motion and prop
blast would do to noise level ??.............

Lynn,
I would like to see a drawing and I am sure others of the group would also !!.............I
know this is splitting hairs but I am planning on splitting my exhaust after the collector to two
mufflers (no good reason other than the Dyke Delta bottom skin has a "Keel" shape (V)
and I want to keep the bottom symmetrical with a muffler (recessed with cooling air) on each
side of the "V" ) and I wonder what size you would use from the 2.75" to branch off to the mufflers ??.........
Again Thanks,

The single pipe would about 5.9 square inches. A 2" tube would be 3.14 square inches. So I would use 2 inch tubing. Most modern V-8s have a combiner "X" fitting in the center of the two pipe system. It produces lower back pressure and a less harsh tone.
I will make some drawings.
