Question, I have a 03 wrx which i picked up used. The previous owner installed a borla exhaust with pipes and he put a boost gauge on the column so since i got it i have noticed when floored it will boost to almost 20 psi and it bounces from 15-20. Is this the same result you had and if so can you lend any insight on what to do because i know its a matter of time till the stock turbo croaks at this rate. Also am i right in the assumption that the larger exhaust is whats causing the higher boost?
