Couple things, the stainless bolts never "fixed" the problem (though often held long enough to make it out of warranty. The article above mentioned unlimited power train warranty - nope; unless you are the original owner of the vehicle, when they offered the "lifetime warranty," most people didn't realize the lifetime portion of it went away as soon as the name on the title changed. There has been, of course other powertrain warranties, but the lifetime went away many years ago. Having done more of these than I care to count, I made a suggestion a long time ago, to install a flex joint in the Y pipe. This would help tremendously with the expansion / contraction issue. The Y pipe also expands away from each end and compounds the tension put on the rear bolts. Anyways kudos to those that are still getting help from dealers on these repairs though the vehicle may not be under warranty, that is something to be appreciated.
