Bought my sti Hawkeye about a month ago with just a prodrive back box, wanted more of the Subaru rumble so looked around the forums and everyone was saying remove the 2nd cat in the down pipe and change the centre section, so bought both pieces only to find mine didn't have a 2nd cat fitted anyway? Doesn't look like its been changed before it was standard factory parts by look of them?

Does it have the prodrive pack ?

If so I think they delete the 2nd cat

Well it wasn't advised as a prodrive, but it has a Pd back box and some stickers on it?

How do you now of it is a prodrive?

Should have a certificate or have some bits on it from this article http://impreza.co/ppp-subaru-prodrive-performance-pack/
