I have a 48 slow jet (was 45) it has the sporty needle ive tried every half turn from .5 to 3 turns out and the carb is deffenitly on the doughnut good because the air cleaner bolts to the jugs which forces the carb on the doughnut.

id take the sporty needle out. had an 05 88 superglide that i put a 48/190main 2turns out on mix screw and that thing ran great. similer set up to yours. i have heard that the sporty needle can cause backfireing. did you make sure your your exaust is sealed up tight?

could it possibly just be the pipes im using their the 200.00 dollar big growl snub nose(short shots) from j&p cycles i talked to my local dealership and they said if its running as good as it is theres probably nothing wrong with the setup they dont know why it would sound bad

it shouldnt be backfiring though. ive run stright pipes on almost all my evos and twincams and i almost never got any backfiring. although once and awhile my efi twinkie would but not alot. i still think its that needle or you need to put in new exaust gaskets at the heads.

You put a lot more air through the filter, and slightly more fuel (through the sporty needle (smaller needle I am guessing))
If you noticed you get more miles from the bike, and your bike feels hotter around your thighs, then odds are you are running wayyy too rich. not good for your engine nor power.
Try instead of changing the needle to change the Jet ..
The 'drag pipes' I am assuming are un-baffled and that should make the situation worse.
