only difference in these exhausts is the sound. the power differences between the two will be minimal. quality is always top notch with these companies.
About hytech headers, can someone clarify to me what anti-reversion chambers mean and do? This is the main difference between production and custom hytech headers.

REVERSION is the secondary pressure wave that travels back up the primary pipes and enters into the cylinder on valve overlap. As this pressure wave travels back up the pipe, it brings with it all the residual gases still left in the pipe. This is what contaminates the fresh intake charge. Enter in stepped headers and ANTI-REVERSION chambers, placed at strategic locations in the primary pipes. These methods are employed to tune the arrival of the exhaust wave and to diminish the effects of the high pressure in the pipes. The results are higher volumetric efficiency and more power.
i also suggest you go read the header and exhaust articles over at team-integra so you have a better understanding of why these headers make power.
