From my dealer point of view :
Intake, exhaust are no biggie and they don't care at all
FMIC is a grey zone and shouldnt affect but if its a boost leak or something they might or might not cover it
Downpipe, chargepipe with BOV are NO NO on the warranty
Tune is not a problem unless it caused the issue (but I still remove my cobb everytime).

Speak with your dealer its the best way to know all dealer are different. You definetely dont want your vin to be blacklisted.
