The ethics of warranties doesn't concern me. He mentioned something about these cars having "black boxes" which might figure out if you've ever had an aftermarket thing installed.
My question: do these cars have these black boxes and if yes (and even if no) is there any way they would know if I had an axle back exhaust installed say if I bring it into them after changing it back to stock.
Again you can call this "fraud" all you want, anyone who knows dealerships know they try to fraud you out of warranties anyway and anyone who knows the mechanics of a car knows that mufflers though they may affect back pressure (and even then there's the argument that cats make all the bp),have little to no effect on the engine and only really deal with sound. So just to avoid any other posts that don't answer my question I just wanted to state the previous.

A muffler delete won't void any warranty. all it does is change the sound.
These cars do have black boxes and they can pull data from it. Typically mechanical over rev.
