i'm going to fit a prodrive ppp downpipe and centre decat to my 03 STI, will this be ok as i'm not planning a remap for a while, will i get overboost or anyother symptoms??? the downpipe and decat are off an 05 STI

 

anyone?????????

 

Personally I wouldn't go down the PPP route. I have PPP and am now changing to H&S Sports decat + ECUTek + remap. (Probably cheaper than PPP all in all, but much better power / response). Don't think you need a remap if you're going for the PPP package, but if you're just doing the exhaust then it's not a good idea. You will need a remap I think.

 

do you know what ppp stands for have a think about it,youre better off with decat ,uprated fuel pump and custom remap to suit cheaper reliable,and more bhp and torque.subaru arent daft...
