Just remember there is also a quality difference between fabrication countries

Depends on which year busa you have. From memory....
99-00 no to minimal flashing
01-03 minimal flashing
04-15 no need for 3rd party gizmo as fully programable

I could be wrong with the 01-03???
If you have a gen 2 with mode switch you can use that to have up to 6 maps available on bike... There is a wire or circuit you bridge via a wired in switch which turns A/B/C into D/E/F lol

I've got the Yoshi Signature R-77 SO SS-CF-CFs - They came with the baffle/inserts unfitted, but my mechanic fitted them for me (You need a die grinder - looked scary). I got them EPA tested and the inspection guy nearly fell over when it passed by a few dBa.

Heaps lighter than the factory pipes, look awesome (I'm a carbon fiber junkie) and sound good. Don't seem to get as hot, either.
