twin pass FMIC

[John1.4]

bumper - undo screws in the wheel arch liners, remove grill to make access to remove lights (you could potentially not bother removing the lights, but it does make a good amount of access)

then unbolt the bumper at both sides, remove from car


in terms of the IC it shouldn't make a difference in the real world which one you use for in and out? if there is a difference it'd be negligable... i'd do whatever is the easiest to do piping-wise
