I also have a half length silencer, this was by choice when I had Monty's custom exhaust system fabricated.
Admitedly Monty is quite loud, so at some point I will likely have a rear resonator fitted just to take the edge of the scream above 4,500 rpm
You could do the same Massi_torini, there is space for a cherry bomb type silencer before the exhaust exits at the tailpipe.
That would probably be enough to make it acceptable, while at the same time retaining some sporty character
