Hows that sound?
The stock flex pipe is welded to the stock manifold. So unless you wanna cut it off and try to make it work then I suggest just buying their flex pipe. I know it's expensive but it's worth it. I think it will save you some headaches later on when you go to install it.
As far as harming your engine and the tune is concerned, the addition of a header I believe requires 10 to 15% more fuel over stock. Don't quote me on that though. It won't harm your motor as long as you don't try to beat up on it. For the tune, you could find a shop to tune it but I rather have someone tune it who has a lot of experience with our car and motors like Tom and Randy
