Dave Platt's "Patriot 3 into 3" exhaust + Penner Tune: dyno tune required?

This is my 2020 Gt when i had the exhaust which i had built on that bike....it is now on my 2022 Triple Black...for some reason the video came out back the front but you can hear the nice sound at least...
 
Did you rip the baffles out?
There are no baffles ....they are just metal shaped like mufflers...the real muffler is in the cat box underneath the bike. I removed the whole cat box and had a new 'Boombox' built...it has the same look as stock but sounds different....plus, there is only one pipe in there instead of two if you have a look.
