Anyone know this exhaust?

[Flrider]

Trying to get some information on this exhaust, brand, sound bite maybe, pros and cons.

Any help will be appreciated.

If I had to guess, someone made those using headers from one of the
few aftermarket Valkyrie pipes that we have heard of... supertraps maybe...

If you lived in Arizona I would say they were made by Performance Exhaust of the Valley, but alas you are in Florida.
