Default Installed Drag Pipes on my 87 FLHTC

OK, I know some hate them, but that's what I went for. I installed L.A. Chopper vortex cones, on them, and we adjusted the carbs. (Too cold to go for a test ride, and she's not tagged yet).
What I ultimately want to do is take her up to the local bike shop and put her on their dyno, and get it dialed in. Does anyone think adding lollipops will add to the low end? Or will I be good with just the cones? (New Harley owner, and this is a restoration project for me).
She start's right up and sounds great! I bought the bike about a month ago, and my friend and I have gone from front to back checking everything. Only thing left is to get my front turn signals working)
Sorry, a bit off topic. A work in progress.

You have drag pipes with slash cuts?! Speak to your dyno shop before visiting them. I would be surprised if they will be interested - and interested to hear what they say! Also tell them you have that air filter....

My Dyno guy said he'd dial her in the best he could with the pipes. He saw the Hypercharger, and liked it. Who knows? I'll leave it at that. I have new jet's (main and intermediate, up and down). I'll let him decide.

Drag pipes are truly more about the look and the sound. If you like them thats all that matters.... You said Main and intermediate jets, is that an S&S carb? If so good choice should tune ok. Yea lolly pops will make a little difference but don't get your hopes up on numbers... A 1/4-20 x 1 1/4 inch bolt will also do pretty much the same... helps to break the reversion a little. Don't forget to post a video......

1 1/2" long 1/4" bolt, with 5/16" nuts stacked on the bolt, will be a LARGE bonus in those pipes.
That is direct dyno knowledge, not something my uncle's friend's brother, heard at the pub.
