yeah they do, but that isnt the only thing that is needed
anytime you put on a bigger turbo there are many things that are needed
FMIC
bigger piping
aftermarket BOV
Injectors
Fuel Pump(s)
FPR
Downpipe
Bigger exhaust
Clutch
Standalone or Piggyback
etc
the most important thing is TUNING.
All of those were done, except I didn't include them because they are more minor upgrades. The exhaust system that I have on the STi is only 1/2 bigger than stock exhaust.
side note: People running 4" exhaust on V6's or lower are dumb because they are actually loosing power because there is not enough back pressure.
