Will a Fullsac D lose low end tq on a 103" with stock cams and decent mufflers?

[CowboyBagger]

My experience is a significant increase in low end torque using Fulsac cores or a different good can.  Always heard that you need to stay away from CFR's, even though they sound great.

Cores are for the stock mufflers yes?, I have RC mufflers(flow better than stock) and am going to use the D headpipe with them.
 What are "CFR" 's?

Sweet looking and great sound but I've heard they can be a pain to tune.

my buddy gots a 13 ultra with a 103 runs the DX and some VH slip ons, bike runs great & he loves it... sounds good also

How's the bottom end look on this one? 100 FT pounds by 2800 RPM.
This is a before and after dyno chart from a 2014 103 limited.
DX Pipe, 2.0 cores in the stock mufflers, S+S stealth AC. Tuned with TTS.
