Replacing the stock overpipe will also make the exhaust louder. (Not sure what you're running for cat-back.)
I would recommend a tune as soon as possible after replacing the stock header in lieu of getting the overpipe and waiting on the tune personally. A good tune+header will give you a nice bump in hp and remove the torque dip.

Thanks! That's pretty much what I was debating on Header + overpipe now and tune asap or just header + tune asap. I'm running stock cat back, since I know it's practically aesthetics and the stock exhaust is pretty decent already. I don't expect the car the get TOO loud if I do header + overpipe with my stock cbe. I was mainly just wondering if I should replace the overpipe along with the header while I'm at it. I wouldn't be able to get a tune till later this year I think.
