I agree fully. I'm personally not into sacrificing low end power for peak power. I just think that Y section looks like it will really slow down the exhaust velocity. As far as I can tell, the HKS goes onto the first flange after that Y, so I have doubts about the HP gain it will give.
Going true dual with an "H" pipe to synch up the exhaust pulses, if done correctly, can give excellent exhaust velocity on a V6, especially when teamed with high flow cats. I know it's hard to gain NA power with breathing mods on highly tuned V6s, so we'll just have to see what the aftermarket comes up wtih.

There is an optimal level of exhaust velocity that is needed to make decent power, and to figure out exactly where this point is is quite difficult. i'd be interested in seeing some before and after dyno charts when this hks exhaust does finally come out.
and it'll be important to look not just at peak hp gain, but overall gain or loss underneath the power curve in its entirety.
