Ok in the latest addition of turbo magazine this WRX was shown with an AVO Turboworld turbo upgrade package provides the real mojo. At the heart is a Garrett hybrid ball-bearing turbo. On the intake side of the system are an AVO blow-off valve and air intake kit, high-velocity intake pipe and a trick front-mount intercooler. On the hot side, a set of HKS stainless-steel headers direct exhaust gases to a common collector, then to a Paisley Racing up-pipe and on into the turbine housing. From there, an AVO stainless-steel downpipe evacuates gases via an AVO 3-inch stainless-steel exhaust system. I was wondering what all the tubinfg is i labeled the two im confused about the red(#1) and the blue(#2) there are others im not sure about can you let me know.
