First, Happy New Year Everyone! 2015 will be a good year for mods, I have lots planned so whether I have the time to do stuff will be the main problem!
Second, I had gotten some requests for a video/sound clip of the Blitz E-ESC electronic exhaust valve in action. Unfortunately it may be a bit hard to tell the difference due to the limited sound recording capabilities of my iPhone, but I think you can somewhat tell the difference. Incidentally, it seems MUCH more quiet from INSIDE the car, but that's probably because one gets used to the drone of the Tomei exhaust at engine speeds above 1200 (so basically all the time) and then all of a sudden when the car is at a light and the revs drop to 1000... silence (ok so it's relative but heck the wife was surprised...)
You will see from the video that what Ninomiya-san (who installed the E-ESC) told me is correct - basically there is no difference in sound from about 20% open all the way to 100%. There is a drastic difference however once the valve closes to 15% or less... here in the video you can hear, when the valve is open at only 5%, the engine sounds that remain at idle, and additionally you can also see that the exhaust smoke (it was really cold outside when I shot the video) diminishes as well.
