ok so here it is:

i run a 2007 FLHTPI 103' with Zipper autotune, Ness big sucker and current exhaust mix of Samson True dual head with Rush 2.0 mufflers (was Samson 32" fishtails till the local HD shop turned them all sorts of ugly colors on the dyno).

current numbers are 72HP/92TQ

getting a Forcewinder intake in this week and now i am looking into a 2 into 1 exhaust. currently im swaying towards the V&H PRO HS. i can not find anywhere on the net any info of dyno numbers of bikes with the pipes im interested in WITHOUT any engine mods (ECM/INTAKE/EXHAUST are the only nonstock changes made everything else is virgin).

so any help backed with dyno numbers (before and after) on a good set of 2 into 1s would be appreciated!

please dont waste my time with "pipe X looks and/or sounds awesome" i am looking for PERFORMANCE based responses!!

ALSO:
anyone running a 07-08 FLHTPI (that was in service (hp or pd) and NOT straight of the showroom floor) that has done anything to get it into the 100+ HP/100+ TQ, id be interested in what worked, and more importantly what DIDNT!!

AGAIN please dont waste my time with "theoretical" possibilities, i want to hear from those of you who have the bike in the garage that has the work already done.
