Does anybody have the fabspeed headers on a 3.6L 996? Does anybody have this in combination with fabspeed exhaust? I'd like to know what kind of noise improvement you have and if anybody has done a dyno run pre and post upgrade?

Thanks

 

Haven't done dyno, but I have the headers, maxflo exhaust and intake. I have no idea as far as performance gains go, since the car wasn;t broken in yet when I put them in. The sound is great from what I hear on the outside of the car, but inside it's pretty tame. Finding tunnels and overpasses to drive under are awesome.
