I was wondering before I looked to much into this if anyone knows off hand. So I want to order a set of catback magnaflows with a muffler delete. Would anyone know off hand if this would void any parts of a factory warranty and if so what? Thanks in advance.
It depends on what your car goes in for warranty for. If you have a cat back and your power window switch goes up then ford CAN NOT deny you but if you have a cat back and your o2 sensor goes up then you may or may not have a problem
If you read this thread again, I see how you posted that they are for sound and have no affect on emissions. I just didn't know if it would knock anything out deleting the mufflers overall.
This is your neighborhood friendly Ford rep here to confirm that the installation or use of any aftermarket product will not necessarily void the warranty. However, if the aftermarket product fails or causes a Ford part to fail, the cost of the repair and any related damages are not covered by your Ford Motor Company warranty. So have fun with your new mods, but make sure you check out the FRPP page: Ford Racing Performance Parts.
