Toda doesn't make an exhaust, so you just answered that one on your own. They make an intake and exhaust manifold, that's it. As far as their header goes, it's a real nice piece, I'd more likely go with that over the Hytech piece, just on it's JDM appeal, that, and the fact that it's less expensive, and it makes about the same power. Hytech exhaust from what I hear is very nice and flows very well. I personally run the Mugen exhaust and love it, and being that it's about the same pricem, I'd probably go with it, as even without a cat, it's quite and not at all raspy, where the hytech does flow a little better, but is more raspy, and a little louder.
Hytech is a great company, and if you have over 2300 bucks to spend on header, tp, and exhaust, then, by all means, I just can't see spending over a thousand bucks for a header. I guess it depends on what you're looking for. But if you're asking my opinion, go with the Toda.
