Does anybody have this fitted or any other up/downpipe with the PPP conversion?
Any gains/recommendations?

 

Didn't know Prodrive made a downpipe although one was rumoured for the STi PPP.

 

Not sure about it either, hoped someone could enlighten me. Anybody else with PPP mated the conversion with another up/downpipe?

 

What MY car? MY01 and greater would need both up and downpipe doing together. PreMY01 - loads of people run full decat systems - almost all have no problems and plenty of power gain.

Lots of people have put a downpipe on with the MY99/00 PPP including myself and it works well although sometimes you have to rebore the restrictor to 1.3mm from the original 1.2 mm if it overboosts - boost gauge recommended if you don't already have one.

On the MY01 and after Scoobysport found that the ignition timing was a bit retarded with the downpipe without the uppipe replacement, but I did not see this when I logged a MY01 with PPP and only a downpipe. Might only occur in certain situations, but the uppipe is well worth getting as well even if it is a bit of a big job to fit - can do both uppipe and downpipe at the same time - takes a few hours. Whilst you were at it you could change the turbo if you felt naughty

 

Sorry guys used to have my signature with all info on other BB's MY02 WRX PPP
