anybody ever install an arc fmic,

[mjjstang]

I was just wondering because I had a couple questions, Ive never installed an fmic before and I know the common answer is its easy jsut line the pipes up, Yah Ive pretty much got that idea, but I have a pipe that pretty much fits the hot side of the ic and goes up into the hole wehre the airbox was, and even has a bracket taht has a hole that lines up perfect for mounting, my question is, how come it has a nipple, about 1" coming out the side, If mounted like this, the nipple is like way up in there where the resonator box was and seems like if it was meant something, should be more up by the engine, You cant even access it from engine bay, you have to get up under the car, also if anybody had any instructions for arc fmic that would be cool, I know I could figure it out myself but directions make it easier.
