The header alone won't make a big difference, since the stock intake and exhaust are so restrictive, but the general wisdom is that if you get all these mods, together they will give you a better improvement than each one of them counted separately.

As for the bracket misalignment, it happened to me. The header is attached to the engine block with at least 4 bolts (if not 6, can't remember exactly) and 2 spring bolts to the exhaust pipe, so it's definitely not going anywhere. I don't think it really needs the extra support the bracket will give it, that's why I didn't worry much about it.

There is a removable steel bracket (painted black in my car) that's attached to the engine and then there is a smaller bracket welded onto the header end. If this weld isn't perfect, as in if it's off my 1 mm, the holes won't align perfectly and the stock bolt won't fit, since it has to be threaded into the DC bracket. That's what happened to me, so I took a smaller bolt and nut and just fastened it like that. Ghetto-licious
