PPP exhaust vs stock

Looked at my exhaust today before I fit PPP and can see it pretty much straight through, does the PPP have a larger bore exhaust ?

AFAIK PPP for STi consists of a high flow sports cat DP, decat mid section and free flowing BB (although I may be mistaken as the STi may have a decat centre as standard). Not sure about bore, but certainly has improved flow.

The standard back box is certainly not straight through! The Prodrive box is.
I believe only the STi gets the high flow cat. downpipe. (plus decatted centre section) The WRX gets a decatted centre section.
