Wow, thats bull... By law, if a specific brand is required to be used to keep a warranty valid, then that company MUST provide it for free... Also the use of aftermarket parts (including oils) can't void your warranty unless they are the cause of the problem (i.e. using the wrong weight oil).
Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)).
So if you install pipes and the transmission blows, your still covered under warrenty because the pipes have little to no effect on your transmission. But if those pipes cause so much back presure that the heads blow off, then the repair will not be covered under warrenty... Make sense?
Its all covered under the Magnuson-Moss Warranty Act. Read more on it here:
