After talking to the caribbean starlet owners. 

This is what is know over there and used for many years this helps stop the small plenium chamber not restrict the topend power.

this was used in the earlier days, especially in jamaica.

i'm not sure if its still popular now

the acis intake manifold is a decent option if you set it up properly
