Blue Streak 2

Guys,

I've got a 2002 WRX PPP with the piggyback chip version. This means it's running @1.2bar boost and has the centre decat and Prodrive Back Box. I've been thinking about the next step and have bought a prodrive sports cat downpipe, £200 brand new off ebay.

Should I:

A). Just fit the sports cat downpipe and if I do so will the ppp map cope
B). Fit the sports cat downpipe and a Hayward and Scott decat uppipe and if I do this will the ppp map cope
C). Do B and have a remap
D). Forget it sell the sports cat and have a beer down the pub on the proceeds

Any help appreciated.

Hi mate, I had same set up as you and was going to fit the Prodrive D/P, spoke to Mike Woods at Prodrive who said that it may cause issues with the map so risky without a re-map, I've now junked the piggyback for an Ecutek re-map as with the piggyback I was seeing a heady 220 HP!!!!!!! with the Ecutek I have 265 HP and much smoother to drive, I've also fitted a de-cat up-pipe since...

Oh yeh the answer is C for sure IMO

From my limited knowledge I believe it is advisable to change the uppipe and the downpipe at the same time on a newage, not just one or the other.

I would think it is almost certain that you will also need a remap but I'm not sure you can do much with the PPP map, (hopefully someone else can confirm this)?

Oh, and personally I'd go to the pub while I decide.

^^ yep, they just rip the piggyback chip out, quick bit of soldering then run an Ecutek re-map

Yep,

Thought that might be the answer, just painfully more expensive. Just feeling poor as it is Christmas.

Bryno what is it like adding the sports cat? Did you notice a large difference?

I didn't fit the D/P in the end, at the time I also didn't fancy the cost of the re-map so held off the D/P, then ended up re-mapping a couple of months later anyway as I wasn't happy with the PPP..

So I had the Prodrive backbox and centre on for the re-map, which gave a good result, then got the up-pipe done later as a safety measure, but it does allow the boost to spool quicker for sure...

I could have done the D/P at the same time as it has to come off to do the up-pipe anyway, but TBH I'm pretty happy with the way it goes as is.. it's circa. 255/265HP with 265/275 ft/lb's torque and I wasn't to fussed about the extra 10 or so HP I'd gain for the cost of the downpipe, but clearly if you want to do the down and up-pipe, best do these before shelling out for the re-map..
