Judging from your old posts I suspect you're talking about a Breva 1100 (and not the smallblock Breva 750).
You my friend, bought the ONE modern Guzzi where they put the damn catalytic-converter in the Y-pipe (collector, or whatever else you want to call it) instead of the muffler(s).
Makes for hella heat at that point under the bike, and yes, where you put your feet down in traffic.
For me the real simple solution (though not cheap) was to install the Guzzi-tech Y-pipe which eliminates the Cat-Con. Unfortunately, it does allow you to hear a little more of the exhaust (well you might like that, but that includes some popping on decel, never really bothered me, but it was a noticeable change).
FWIW, it's a beautifully made piece:
