the difference is so small but it is a difference. i guess its all personal preference. you will gain the peak HP but you do lose peak torque and a little bit of (IMO) usable power.
i like this setup now, i just want a tiny bit more up top, which i think i can gain with a better UIM. i was comparing the escape manifold (mazda 6 is the same thing) to the taurus 2004 and it looks like the escape manifold really hurts the torque from 4000-6000. i can't see losing that for a couple HP up top. but maybe my engine will respond to it better. i'd like to try it out either way. its only 114 bucks new :shrug:
