GoPro Hero3+ mic vs Olympus ME-51s mic from outside

Out of the box, the GoPro Hero3+ captures really good sound. I wanted to make a quick minute long video just showing a direct comparison of the GoPro internal mic vs the Olympus ME-51s external mic. To make the video I simply mounted the GoPro on a tripod using a tripod adapter mount and recorded around 20 seconds of exhaust noise with the GoPro in a skeleton housing. Then, I plugged in the 'GoPro mini USB to 3.5mm adapter' and Olympus ME-51s external mic. The tripod is approximately 2 meters from the rear of the car.
