You get a 36k warranty that WILL NOT be void if you change one part. The warranty on that part and anything directly related to that part that could potentially be damaged because of the modification will be voided but thats using common sense. If i replace my exhaust they are not going to give me a free exhaust replacement if i have an exhaust leak or my o2 sensors go bad because of illegal exhaust.
Dealers talk a hard game but in reality the law protects your warranty. There is a federal law protecting people with their warranty claims and it states that a damaged area of the vehicle has to be caused by something the owner modified. In other words it has to be proved that there was a cause and effect relationship between a modification and a damage to the vehicle.
If that wasn't the case the dealer/automanufacturer could simply say oh you put new springs on your
suspension your entire vehicle warranty is voided including your powertrain. What in the blazes would your springs have to do with your engine and transmission failures?
