I think Mr. Consumer might have been on the right track by resorting to the credit card on which he charged his purchase. Besides the price protection he cited, most cards offer double-warranty protection up to a specific time period. So does that mean his muffler would be good for two lifetimes? Yeah, right. I would have called his credit card company to see what the protection might have been in that case; they may have some arbitrary time limit assigned to the free warranty extension in the case of "lifetime" warranties, which the credit card company must know is bogus...unless, of course, it excludes auto parts anyway, as was already his experience.
