A popular performance-minded aftermarket modification is to replace the piece of flex hose with a straight metal pipe and two 45 degree silicone boots. I've seen a few guys do that, usually in conjunction with an Ole Smokey BHAF mount.
I don't know how that's supposed to flow better than the stock flex tube, but if the stock tube's broken it's probably cheaper to go that route.
