lol i was changing out my seatbelts last night and went to remove my oem seatbelt and of course it had the airbag wires attached and I cut those off because my new EP3 seats didnt have the sensors and I plan on getting a new steering wheel so no point in them anyways.... my question is....

when i pulled the seatbelt off it had a black cylinder attached to it that said...

Warning this device has explosive material inside. Dont not tamper with or could result in serious injury..... something along those lines....

wtf is that?? I could just leave them on there.... but i would like to take it off.... any suggestions on how to remove that thing??
