agree
the boost controller, hiflow cat, loud exhaust, pod kit, shiny cam gears with pretty colours etc will likely get you caught up fitting mods that go against EPA etc. once they identify these, then a full check might pick up different ECU, emissions out of whack, and so on.
its unlikely they would pick OEM turbochargers vs upgraded replacement bolt-ons
be sure to note the new garretts etc would likely be nice and shiny, vs original stockers with 100,000kms on them (dirt, oil etc on the compressor covers) so if you remove the heat shields / shroud etc it may be dead obvious even with replacement bolt ons
i guess you could argu the stockers failed and you have to replace with garrett OEM's
