I currently have fullsac DX head pipe and D&D 4"" mufflers on a 2015 SERG  that has the 117 upgrade with the 585 cam.  The D&D mufflers sound good but they have 2 1/2 " cores and I want a little more low end torque and I also think  the bike would make more power with a 2-1.

What pipe has proven to be easy to tune and provides good Torque and HP?

The headpipe you have works well- switch to Crusher Mellows to pick up the low end without losing much above 5500.

Put your orig mufflers back on after adding a set of 1.75 or 2.0" Fullsac baffles.

If you go 2-1, I have had better performance from the Drago over the D&D an avg of +5 or better utilizing the 2.5 baffle and the 2.55 collector.

My FXR4 S&S V111  has a set of custom S.S. stepped 2 into 1 pipe.
My Road King V124LC build, I ordered a set of RB Racing LSR 2-1 with 2" headers. Chromed.  Still waiting for them.

im running a dragos 2 on my lill 110, it works good...you may be money ahead if you get a different muffler set and good tune

I have not heard of Drago 2-1 . Is the pipe easy to tune with?

[Doc 1]

You can run any pipe you want but you won't pick up any lowend tq with that 585 cam.....just being truthful with you....

I did not use the SE 259 that came in the HD kit as I thought the 585 would perform better down low. The bike runs very strong unless you bog the motor down low. Then it has some spark knock. I thought part of the problem was too large of baffles in the D&Ds
It has been dyno tuned but the numbers are off from what I have seen posted on these boards.
107 HP
127 TQ

Torque numbers are about right for a 117 presuming that is what you have, the hp can be the combination, the tuning, the pipes ( backpressure), the heads or even the cam,

I am very happy with the SuperTrapp SuperMeg 2-1 on my Ultra.

X-2 on that Don. CVO cans, 2.25 cores, new mats & screens from Steve &  DX Pipe . Making  100 Ft.Lbs  @ 2000 , 136 @ 3600. Pulls hard, pretty happy with the SE 585 cams . 136/121

[CVCVORG]

136/121 are good numbers.  Texas Can you share more details on your build and who did the tuning?

New RB Racing LSR 2-1 with 2" primary headers on S&S V124 LC motor.  Heat shields not on yet, motor has not been started yet. I can't wait to break in the motor!

Another pic. Seat, bags, batwing and tour pak not mounted yet. Did 5 heat cycles mechanic getting ready to do a test ride. He didn't like my seat. Pipes sound great!

My build is 117 HD drop in kit. Zero decked cyls. Front was .012 in the hole back was .009 . Cometic .030 Head Gasket, 2.120 intake from MVA head. milled heads .018 for 92 CC Chambers. No head work to speak of , just good clean up. SE 585 Cams, Fullsac DX pipe, CVO cans 2.25 Baffles .

Rode to Illinois and back over the 4th of July, 75-80 most of the time. Average 34 -36 MPG, Got stuck in traffic in St Louis for about 15 minutes 95 degrees, no problem. Had to run 91 Octane some of the time, not a peep out of it. Pretty pleased with the way it came out. Some sharp guys, doing good work and a good combination for the bike and the way I ride.
