I have also been interested to see how they match up against each other powerwise. I have hytech style on my B20VTEC and it makes good power however the ground clearance is pretty shit as the bottom two primarys hang lower than the sump. I have already scraped them pretty bad and worried if I lower my car I may end up denting them as well . Also, FYI the highend style is a copy of the SMSP header which are suppose to make similar power to the hytech design.
