Hmm, always thought they were slightly larger

that is a bit of a myth i think (same with sr20 na t/b's being bigger than turbo ones. only applies in 1 model, which i think is the s15). seems to be plenty of people who think it is the case, but pretty much no one has ever properly measured

70 mm outside diameter. Buying a piece of hose for my car now, so measured it and yeah, 70mm.
