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

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.
