DP Outlaws or Revo Twin 6"

Hello can I ask who is running Dave Plat Outlaw exhaust and who is running Revo Twin 6" exhaust. I am looking to just fit the end cans and leave the Triumph middle pipe/muffler. Been hearing a lot about problems with the Outlaw system especially if you fit the de-cat pipe as well with the left hand exhaust sooting up??? Any info appreciated.
