Power Tone exhaust systems

[dd74]

I'm about ready to give up the Bursch on my 911. Question: I know a fair bit about the advantages of a dual-in-dual-out system, but has anyone out there had any experience with a Power Tone system? I've seen it mentioned on the Pelican Board, and it looks like it might be lighter than systems such as a Dansk or Monty. This is their link for more information:

I think the Triad dual-in-dual-out is a nice looking system, too. Does anyone have any experience with this. I'm not looking forward to chopping up my valence, but will do it if the increase over a Bursch is worth the trouble.

Thanks in advance.
