And wow does it make a difference. I mounted it to the rear bumper right above the exhaust, and this is what I got from a run through the first two gears. Keep in mind that this is a bone stock exhaust on a non-M Z.
I got the mic on Amazon for $68.

I should preface all this by saying that I did a quick test of the mic inside the car, and it didn't pick up much sound at all. I've already removed most of the foam from the sound generator tube and bolted on an intake, so it's not like it's all that quiet inside the cabin. I'll try putting it closer to the footwell to maybe pick up some more sound, and post up a comparison between the internal and external mic when I do.
I'll also be giving it a go on my motorcycle with a race pipe later this week. Can't wait to hear what that'll sound.
