Is there a good head pipe that would work?    Fullsac DX?

fulsac DX with 2.0 cores will work for just about anything you need.  Here is one that I had handy 110 our cam and the complete fulsac system

with true duels you will lose a lot of hp and torque

I went with the fullsac DX header and 2.5 fullsac cores and then switched to cfr's no problem ....doesn't like under 2000 rpm...but I usually don't ride that low in the rpm range ...every were else it's a beast
won't go to a true dual ....always lose hp and torque. stick with a 2 into 1 or a 2-1-2

To illustrate what others here are saying about the CFR mufflers, attached is a dyno sheet taken from GMR's Facebook page of a 113 kit comparing CFR to Crusher mufflers, all else the same.  Note headpipe is Fullsac CX pipe, but results would be the same for any good 2-1-2 headpipe.  You can clearly see the torque and hp dip below 3K rpm that results in the "soft" bottom end people refer to. 

If you are more concerned with the sound and don't care about performance down low and like to run higher rpms, then the CFR's would seem to work for you.

my bike (seat of your pants) feels better now with the CFR's then fullsac cores
like I said before doesn't like to luge under 2000 rpm....get it to 2500 and above ....performs better at mid and high rpms

You stated in another thread that you only had a stage one download.  There is no way the bike is anywhere near properly tuned with a canned download.  If you are just swapping mufflers and evaluating, it's not fair to make statements that the CFRs are better than the fullsac cores.  Get it properly tuned with both setups and I can guarantee that you would stick with the fullsac cores over the CFRs. There is no comparison between the 2 when properly tuned.

There's something to be said on how YOUR bike feels to YOU.
I did the "real" dyno tune on my '14 (and earlier bikes) got all the power it could handle, then, "de-tuned" the bike with stock a/c cover, stock mufflers (re-cored by Fullsac) conservative TTS tune all in the interest of gaining a well-mannered touring bike to fit my needs:
1: towing torque
2: quiet power
3: stock appearing
It's taking me a few years to figure out what THIS bike will be used for. I have my other bikes that I use for different riding. If I want "loud, fast, touchy, high maintenance" I have a bike for that also. I don't ride that one much! Must be the old age thing? LOL
JMHO of course, to each his own.

sorry it's how I feel....started off with a complete fullsac setup and download on my tts tuner from steve ......had it for the last 3 years.
I feel with the CFR's it just feels and pulls better at higher rpms and top end

I have a TTS tuner so I can auto tune and dial it in ...but I know what everyone is saying about getting it dyno tuned ......just never had a problem runs good ...pulls away from my friends bikes and no popping on deceleration.
not misleading anyone...how I feel from my exp. been riding bikes / dirt bikes / atvs from 5 years old
