Okay, I don't understand that statement. You do want a header but you don't want an exhaust? Do you realize that a header is part of the exhaust system. Further more did you know your Si already had a header?!
It is a shorty header but nevertheless a header and not just an exhaust manifold. If you do get a header (I would recommend the Vibrant header and Cat combo that is going to be out real soon) I wouldn't recommend using the stock cat back since you will be defeating the purpose of the header in freeing up back pressure. The stock cat back is pretty restrictive. If you don't want it too loud I would suggest a Greddy SP2 or a APEXIs WS II system. Those are about the quietest cat backs out there which will still gain you some ponies. I would still invest in an intake whatever it may be.
If you look at your stock intake it is the most involved tangeled mess you have ever seen. Big old ugly box on top going to tubing leading down to the front bumper where it goes into another box called the resonator and then exits into a small opening. You are choking your car if you are putting on a "raceheader" and not letting it breathe. Sure you can do it but why?
If you want to keep the car stock just leave it alone and don't worry about a header and the hondadata relflash. Just put in a ZEX Nitrous kit and use it with your stock set up. You can be stealthy and stock when you want to and get a noticable kick when you want it
That mod will give you the best of both worlds and a noticable gain in feelable performance. Plus it is cheaper than a hondadata reflash
But it's your car and you can do what you want to with it. I just don't understand your logic if there is any.
