No it won't void your warranty. When you get it done, leave the old O2 sensors in for a couple of months to let all the crap burn out of the exhaust. The engine light will come on, but only because the sensors will be contaminated. Replace them after a couple of months. They aren't cheap though. You may be able to get them done under warranty, some people on here have.
Pacemaker extractors with the Pacemaker twin system will work well.
