No modification to the exhaust after the Rear O2 sensors will void warranty unless Ford engineers can prove that your modification has directly caused the damage.

For example, if you crush the tail pipe and the engine is damaged, then the crushed tailpipe is likely the culprit. Ford won't cover that.
