No. According to the warranty guide, your exhaust is only warranted from the exhaust manifolds to the cats, after that it's open season. That's why we see all of these cat-back systems, they don't fool with the emissions and they don't void the warranty.

 

Ford man, where can I get a warranty guide (is it with my owner's mannual) I like to have as much info as possible, when I need it so the dealership does not try to mess with me.

Mine was in the glove box of my pickup when I bought it. I guess hit the dealer up for one if you don't have it. It's a separate publication from the owner's manual.
