I have seen the video clip of a F6B with Cobra Truck Stacks and really love how it sounds.

I tried to find them for a purchase but cannot find anyone selling them.

Are they discontinued pipes?? Replaced by the 6-2-6 exhaust?
I guess I'm the minority here, but I really don't like the look of the 6 pipes in the back.....

Do Bassani, Rush or Torq Master sound like the Cobra Truck Stacks???
