I've been rocking one for the past month. Install was pretty straight forward and no real issues. Don't forget a new gasket set. I had the black WRX oil filter (bigger diameter). It cleared but BARELY. I've since changed it out a STI filter.
I had plans to measure the runner lengths prior to install, but the new part excitement bug bit and I forgot.
I'll try to do so the next time I'm under the car.
In regards to power; I'm finishing up my etune now. I can't qualify the power gains, but its a lot more fun to drive (running max of 18.5 psi with stock dp and air box on 93). But I didn't really buy it for the power. My goal was to get a ELH to merely remove the UEL header. I considered this and Killer B 2-bolt. I really was torn between the two and could have gone either way. But I couldn't find a 2-bolt in-stock and felt it was a bit overkill for my needs (only power mod I plan on doing).
Coasting in gear or engine braking is a smoother than stock. Not sure if that is from the tune or the header. My car also is smoother at idle (stick shift vibration is reduced) but again not sure if that is the header or the tune.
In regards to sound; I love how it sounds (can't compare to much other than stock). It sounds more efficient, hear every cylinder now, but not wimpy either. I don't hear the rumble anymore; WHOOPEE!. I now just hear the engine at highway speed (even with sound tube deleted) and not the exhaust (sound proofed the rear deck, tire well, and under the cargo tray). At warm idle I hear the exhaust just a bit (deep sound still) but cold start is louder than stock (can really hear the air pump kick off). I like the sound the most when accelerating in the mid range. Plan on sprucing things up a bit with a cat back sometime soon, just don't know which one yet.
I have a dB meter and will post some readings if I remember later this week. I don't have any means to take a video other than a crappy smart phone.
