Has anyone done Borla long tube headers with their x-pipe? I am having the worst experience with Borla on an ill-fitting x-pipe. Original piece is too narrow by almost an inch; the headers will not flex that much. Borla looked at the photos and their engineers said it was a faulty piece and took weeks to send me another...same exact problem AND worse, it's too narrow AND too long now. And, can't always get an email reply when I check on the status. WTF!?
