My Milltek is exactly what I was looking for. Subtle, not droney on the motorway and sounds decent when I give it some beans. My brother seemed to think it sounded decent when I gave it some beans when he was following me the other day.
To get it sitting right you have to squash the mounts for the mounts if that makes sense or just push them left/right.
With a custom remap I saw +8bhp. I'll leave it to others to decide how accurate that was and how much( if any, likely little/none) of it was down to the Milltek.
