I have an opportunity to get some Screamin Eagle 2-2 slip ons, Fatshotz or Nightsticks for a good price. Both still have stock disc, security screw setup.
My bike is a '00 FLTRI with 95", ported heads, cams, S&S 2-1-2 head pipes, V&H HO slip ons. Bike sounds great.
I've run SuperTrapps in the past and like them. I know they wont sound as good as the V&H's.
My plan is to modify the SE slip ons to whatever amount of disc and end caps, get some back pressure. I want help my low end.
From what I have found out is the FS have a perforated core and the NS are a solid core. So which of the two styles has the most performance potential?

 

I have had both and like them both either one will be more that enough. As for sound they sound better than V&H and are different.
The Fatshotz do not use the end plug on the 2 to 2 pipes only on the 2 to 1.
It you want more exhaust flow add disk if not leave the stock 10 in.
Currently I have the night sticks on my 2013 with fuel moto 2-1-2 ceramic coated header. I like the set up, not a big fan of the all black thing but black exhaust worked out on this on.
I have had people ask how the exhaust gets out .

 

It really is a matter of sound. Both are the same (with same disc and end caps) except for perforated core on fatshotz. Fatshotz will be quietier. Nightsticks may flow a little better?

 

Did some more research and it seems the FatShotz would be the way to go. Looked at the SuperTrapp Screamin Eagle tune kits.
The FatShotz kit is extra discs and associated hardware $79.00, Nightsticks is extra discs and also requires perforated baffles $238.00 for the upgrade. It would seem after the SuperTrapp mods they would be about the same in performance.
