Question Screaming Eagle Tunable Exhaust

I purchased my 03 Wide Glide a few days ago and it has a Screaming Eagle 2 into 1 exhaust that seems to be muted. I figured that it was because they must be street legal. Looks like that is not the case, because the exhaust is labeled for race use only and after further research, it is a tunable exhaust with these disks (20 of them) that I guess you can add or remove to change the exhaust note. Well I removed 10 of the 20 disks and the exhaust note is still weak. So I decided to start it up with no disks and back plate on there at all and it sounds great.

Question is for those who know anything about these tunable exhausts, would it be okay to run it without any of the disks and the back plate that retains them?

Thanks

Sounds like you may have a SuperTrapp performance core. Link below is to a page with a description of how they work:

I'm running 12 disc with the open cap (looks like cone with hole in the end). The first link I posted above has images of the system, the bottom image has the open cap.
With the open cap I get a good exhaust tone but not quite as loud as strait pipes also still have a bit of back pressure. If you start changing the pipe internals stock or the performance core, the fuel mixture requires adjusting. With my S&S carb it's just a matter of changing a couple jets and turning a couple screws. I don't know what is involved on the fuel injected TC's.
