I guess the Hytech exhaust combo should be the most extreme exhaust for CL9/CL7 atm. The header is longer tube design which tend to be racing header and works even better with aggresive cams. I want them myself if only I haven't got full exhaust system atm.
I believe, you have seen the hondata tuning guide for TSX. In their dyno test there is comparison of Comptech header+ airbox+reflash yielded the around the same result dyno compare with toda header +injen +vtc + tuning. The only difference is the mid range power which is caused by VTC.
Anyway the DC sports and comptech doesn't come with test pipe or stock cat elimination compare to toda which could cause higher output.



I'm still waiting for a Hytech headers dyno. The only dyno I've seen was the works including cams, valves, springs, retainers, intake manifold, exhaust and cat as well as the headers.
