Here is Racingline's response (1/30/2008) from an e-mail I sent them,
"a new sample is on it's way back from the welders as we were not happy with the results from the first sample. The y merger was not up to par in our opinion so we had the bender/welder make up a new sample. That sample should be ready next week and dyno again soon after. Production should still roll out sometime next month.
Thanks,

I am getting impatient as well even though I am not looking forward to the frostbite inducing install on my driveway...
