3 into 1 exhaust

[Mtrhead]

I was doing google's looking for info on triples with single exhaust and came across this site. Probably more info here than anywhere but still not too much on the inboard hydro exhausts utilizing jetski motors.

Few questions:
#1 Anyone have experience with this Skidoo manifold design? it physically displays the plugging theory for sure! (it appears to be a better looking option that the traditional LOG from the Yamaha motors 1100/1200cc)

#2 Anyone have pictures of the exhausts on these 1 litre mod hydro's? Specifically the triple jetski motors with single pipes. (found this picture with a manifold design but not the chamber/megaphone)
