I have bought a 2004 wrx with the wr prodrive package (supension, back box, panel filter,hoses,ecu) ..I justed like to know will it have the prodrive high flow cats (both)...

 

Yes and it'll have 1 sports cat now with a prodrive decat section to replace the second cat

 

Thanks

 

Wont have that I'm afraid. Prodrive pack doesn't change exhaust at all apart from back box.

No suspension changes either.

You will have 3 cats still, one up, one down and middle one. All standard wrx ones.

 

All i know is with my blob sti, with my ppp pack I had prodrive backbox, 2nd cat removed with a decat pipe, walbro 255 pump and an ecu refresh, go on the prodrive website, they have the prodrive pack on there.

 

Ye though so i agree with jlarcombe , but i have blue springs on standard inverted struts so i would say this is a wr upgrade at a extra cost on top of the ppp package....
Mines just a wrx ppp NOT a sti ppp jimbo14, thanks

 

Yes mate, you got the good springs. There are not many good ones out there as they over lower the car and upset the balance.

I never did understand why they had to put 3 cats on when the car can pass an emissions test with just the one in the down pipe.

 

apparently just Subaru's way of keeping emissions down. The uppipe cat keeps emissions down while the engine warms up, once warm the other two will take over. Well this is theory. Obviously explains the Wrx but not the sti ppp

 

If i had the 2nd cat removed for a ppp pipe would i c any gains would the CEL light come on and would i need a remap and same again with a ppp cat and ppp 2nd decat..

 

You are better off just replacing all the cats with straight through pipes and getting your car remapped. Of course your car will fail its MOT so you may wish to run a sports cat downpipe instead.

CEL light will come on and stay on so will need sorting. Can probably be done at time of mapping. You will need a remap for all these changes and to make use of the easier breathing system.

 

I'm fairly confident that the PPP on a WRX *did* remove the last cat in the system, replacing it with a straight through pipe. For some absurd reason, the heat shields are re-fitted onto the WRX decat pipes, so it looks as if they've still got a cat when in fact they haven't.
