I think I'm finally going to let go of my AA X pipe as I want to try something different. Might go with the Fabspeed or Akra. It will go for $2000 + shipping. Preferably someone in the US. I have an Eisenmann Race with the X pipe and it sounds fantastic at 4000+rpm. I dont have the original box but will have it packed right when shipped. pm me if interested as I dont check threads often! thanks!
