The chip made little to no differance in the sound of the Ex. ( I dont know if you were asking about the intake or the chip ) The sound differance with the intake was very noticable.
Do a flasher instead of a chip. More flexible options and less hassle to install. The only advantage of a chip is that you can switch programs on the fly whereas you need to take a minute or two while stopped with a flasher. No big deal. I have an XCalibrator2 with 3 of Bama's programs in it any any given time. The best thing about the XC2 is that Doug (bama) can send you new tunes via email and you can upload to the flasher. With a chip, you'd need to uninstall the chip and send it back to Alabama for a reburn and be without a custom tune the whole time.
I've owned both a chip and a flasher and much prefer the latter.
I have to eat my own words on that one. While this is true of high performance engines such as the one in my 92 Ranger I wanted to update the thread so others searching would not be turned off by an open air filter setup on a milder or even stock motor. As it turns out the front bearings in the three idlers on my 94 Ranger (stockish 2000 Explorer drivetrain) where rusted or otherwise damaged and had a very strange sound that sounded exactly like the air sucking noise from the filter. I got suspicious once it started pulsating in and out and pulled the serpentine belt to find the engine was dead silent. Pressed three new bearings into the three idlers and problem solved. This motor had never been fired up by me with anything other than my custom intake and no matter how hard I listened it sounded just like the air sucking sound. Sorry about that.
Good thing about the Volant kit is the covered air box, open air filters in the engine bay pull nothing but hot air, kinda makes the "cold air kit" an oxymoron doesn't it?
A TRUE cold air kit is going to either put the filter in the fender or in a insulated box to keep IAT's down. Just putting it (conical filter) under the hood will get you more air flow than the stock panel assembly but it will negate any power because of the hot air.
