Managed to get hold of a prodrive ecu for my 99 UK impreza . Also got an STI y pipe so just need the centre de cat exhaust section to complete the kit. My question is which centre section to get. Is the prodrive centre section the same as the p1 and Sti centre sections? Will any aftermarket one do? I want to get a resonated one as the car is my daily driver so don't want it too loud plus the prodrive one was resonated I believe .

Scooby sport one any good ?

 

I've got a non-resonated straight through centre pipe on my daily driver '99 UK PPP, with a standard Sti backbox - no droning, very subtle and easy on the ears. With a Prodrive backbox the noise was not over loud, just irritating.
You'll really like the 20% increase in mid range torque the PPP brings.
Hope you've bought the correct ecu.....

 

The one I have is A18-000 dix.

Is that the right one ?

I have a prodrive back box so maybe best going resonated as I do a lot of motorway driving.

 

Yup, that's the right one, you're good to go. Plug and play.
I didn't really like the sound of my Prodrive back box.

 

Scorpion resonated center section

 

I'm running with non resonated center section and racebox back box and car runs well and no drone

 

Just got this one for now . Not sure if its resonated , has a bulge in the pipe work. Will do to get me going as it was cheap.

Fitted it all today . Took me about three hours in total on me own on the floor. Only ball ache was rounded and rusty bolts on the exhaust , cat ones snapped and one rounded on the backbox.

Cost me around 300 all in with exhaust bolts and gaskets. Comes on boost a bit earlier and harder and pulls nicely so very pleased .Good bang for your buck if your after a modest safe increase on a daily runner like me.

Sounds spot on aswell doesn't seem too loud but defo sounds angrier . Got the commute to work tomoz so will find out what it's like on a long motorway run.
