Even if they do seize I wouldn't think it would be impossible to free them again. I cannot see wiring or anything else being in danger unless the exhaust gas were directed towards those areas, pointed down like these I see no issues. Sounds good and having the ability to sound stock with no drone has got to be VERY nice too! Can you simply crack them or is this a binary on off installation? I've seen them setup to be boost sensitive and other things as well, not sure how much sense it makes to get too crazy...
