I just went by ford and ask if I can get Long tubes and a mid-pipe and still be under warranty. I talked to the Service Manager and he said I could! But then I went by a muffler shop and ask how much $$$$ to put in long tubes & mid-pipe and he said "We don't install headers, we just install the pipes that hook to them" Then he said installing headers on the car would void the factory warranty and throw off the computer and o2 sensors etc.!!?? They just said at the dealership it wouldn't!!!!!!!! They just said it would void the parts that got replaced.[sm=smiley5.gif][sm=smiley5.gif][sm=smiley5.gif][sm=smiley5.gif]

 

get it doen at the dealerand get the warranty garranty in writing.
