It is Brand New (other than my one failed installation attempt, so there may be a scratch or a scuff on it, but it was driven about ten feet before I realized something ain't right and I did more research)
I can't remember if I purchased from Torque Solutions or Torx Racing, I believe I made the purchase on ebay.
As far as I know, the fit issues are the same as the Perrin it copies. The stock inlet pipe is not long enough to properly seal, so the slightly longer silicone one is necessary. The gasket that was included seems like it couldn't seal anything, so per the recommendation of this site, I purchased the Mr. Gasket part that fits and seals perfectly.
I never got the chance to install before I traded in my LGT for a BRZ
