Here it is, the controversial port divider!  The theory is that if the siamesed #3 & 4 exhaust ports are separated, the resulting "balance" will help performance.

 

If used, this piece must be installed per the manufacturers instructions!  Do not do it any other way.  Tack weld it in with a nickle 99 rod on the right, left and bottom.
