I don't have the exact measurements. I would have to go and measure. The 3 inch portion is short. It's definitely less than 6 inches long. Most of the pipe is 3.5 inch and it tapers to 3 inch just before the throttle body. If I had to guess, the 3 inch portion is probably 3-4 inches long.

I do not have pictures at the moment. The results in the above graph were with the PLM header. The skunk2 header made the same peak but performed worse in the mid.

you should be able to access the photobucket images in your profile. they just wont host 3rd party anymore

its funny how many people dont belive me when i did same thing on b series. i did a stepped intake with tuned length also +vstack
gained like 4-7tq across the board
then flanged the pipes and smoothed everything out gianed another 1-2tq
and actually build positive pressure at around 6700-7200rpm on a type-r motor
total difference from stock TB and basic ebay short ram was close to 10 whp in vtec and much better low end tq

I checked my photobucket account. The pictures were not hosted there. I looked at the dead links and realized the pictures were hosted on my imageshack account. I logged in but all of my pictures are missing. I emailed their support staff but I have no idea if my pictures can be recovered.

And yes there is a good amount of power to be gained with a properly tuned intake pipe. As far as the throttle body goes, there is also power to be gained. The only change I've done on the car since this last setup was switching from the 70mm throttle body to the 74mm throttle body. I never got it back on the dyno but the logs show over 100 kpa throughout the rpm range at full throttle. The engine doesn't fall back in to vacuum.
