So you bought the Hytech. The bungs are 1/8NPT, not O2 bungs. For testing a proto manifold and individual cylinder trim in an attempt at lowering BSFC for enduro, T25 specifically. Never happened. Gorgeous piece though. Good for an S/C or high output N/A.
Run at least a 2-3/8" (RB) but 2.5" exhaust preferably. No gains with 3" tubing. Also no gains by going super loud, super low restriction mufflers. Run sensible muffler/resonator.
That header would be happiest on a big P/D blower or C30/C38 Rotrex. If N/A at anything under about 160whp, the primaries are too big (but the correct length).
Anyway, nice to see it found a home where it will be appreciated for what it is.
