Call me stupid, I was told by a buddy who talked to one of the techs at our dealership that the chargepipe a typically break because the engine flexes and not so much from boost pressure. So couldn't you theoretically solve the issue by removing chargepipe and coating it with that crazy ass Line-X stuff that makes things industry table and then fix the issue
