Hi
I got done by the EPA for loud exhaust and needed to quieten the pipes. You cannot buy quiet baffles for V&H Slash cut staggered.
In the end I made my own. Still not quiet enough, but it has improved the note.
My ride is a VN900, but the problem is universal.

agree a completely gutted system maybe loud on that bike but it would perform like complete crap
good to see you got some boots on while working on the bike.
Standard (ish) baffles:
