No, the car is not stock, but the mods are not extensive at all. I won't post mods here but feel to PM me. The most important mod is the 'driver' mod!
It's just a $20 Mic I found on Amazon

There's no special wiring at all. I just have the mic cable go into the car, through the back seat and out to the license plate area. I use painter's tape to secure the mic to the space next to the light for the license plate.
