Having ridden in the "8Complex Monstrosity 888", I think can give a fair view on the performance of the intake.
That fun low end that pushed you back into the seat is gone. Mind you that this is w/o any kind of A/F adjustment or exhaust mods. But, the car accelerates and sounds like a Honda on its second cam profile. You know what a Honda sounds like with a loud exhaust? Well that is exactly how the INTAKE screamed. All that missing low end torque kicked in when the car starts getting sluggish after 4500-5000 rpm, pulling the car quickly to redline. Great for the racetrack. Real poor for the autoX track.
For daily driving? Only if you drive like 8Complex.
