Hi All, I was having a clear out from my in-laws garage and found a resonator section from my old Sti PPP UK, it was attached to a Prodrive branded Back Box - what I wanted to know, is this piece of Pipe standard or was it an uprated version of the standrad resonator pipe - if anyone knows please chip in...........take care(still has heat shield on and what appears to be a small square "silencer" attached )
