Just installed this system yesterday with Cobra PowerFlo intake and fi2000 tuner. For reference, I had stock pipes with 4x 1/2" holes drilled on each. The Tri-Pro sounds much better at idle, and on the throttle. Coming off throttle though, there is a very raspy sound to it. Sounds kind of nasty, but not sure if in a good way hah. Overall sound is louder than drilled stockers, but quieter than complete debaffle. I'd guess the noise level is somewhat less than most of the aftermarkets just based on videos I've looked at.

Yeah sorry for the poor quality of the videos. I just wanted to get the sounds captured in the same environment so the comparison could be made between stockers.

I just took a quick 30 minute ride with my half helmet, and I'd have to revise my earlier assessment that the tri-pro is louder than drilled stock. Seems like it's about the same volume. Something about my full face helmet made it seem louder maybe. I can get some better quality video if anyone is interested.
