Hi, can anyone tell me the cpsi ratings of the standard cats fitted to an 07 sti ltd type uk,and also the cpsi rating of the prodrive cat that is now fitted?
Am i also correct in thinking this version has no cat in the up-pipe?
Finally,does anyone know the flow rate of a prodrive fuel pump in litres per hour?Iv'e tried to ask prodrive this,but no one seems to know!!!
