Installing ANY aftermarket part will NOT void your warranty. Per the Magnussen Moss act, aftermarket parts cannot void warranties, as long as said aftermarket parts are not the CAUSE of a failure.
I.e., you swap your exhaust out, and your RMS starts leaking - the exhaust can't cause that, so your warranty still covers the RMS.
