Two thoughts to bear in mind:
1. The short answer to the question as you have worded it: no, the Ramifier will not "void" your warranty. that is, automatically or without contest.
2. As a matter of practicality, any power enhancement has the potential to be named as the cause of a drivetrain warranty]
Concepts (1) and (2) can and have been interpreted and applied differently depending on the dealer. The overriding principle is Moss Magnesun (sp): an after market part cannot itself (because it is after market) cause a warranty issue and must be proven to be the cause of failure before a warranty denial.
But some dealers slap on a restricted warranty as soon as they see physical evidence of a box. On the other hand, some dealers' service departments sell mild performance boxes, install them for the customer,and go to bat for the customer if there is drivetrain failure with a box on there.
But in general, be aware that you pay in order to play, you are your own warranty station, and that this question comes up about every week
