997 fabspeed exhausts

[charge]

Anyone out there heard a 997S with one of these sport mufflers on, or have any veiws on alternative sports systems.
I am on the verge of taking the plunge on a 997 as the sale of my boxster S looks promising.
I just want to hear the flat six howl, and dont know whether to order the fabspeeds someone on another thread linked to, or whether tubi's sound better.
Also i dont have bottomless pockets, and tubi's have always given the impression of quality, but at a price.

I have the fabspeed medium noise on my tt and its LOUD. It drone between 1800 and 2900rpm like a bitch. AWE tuning make one that is drone free.
