Did this make you'd car louder?

Yep. The pipe is a lot thicker so the sound is deeper.

Holy crap. Your car definitely is slammed, I could have sworn your pipes were just dragging along the car the whole time.

I find that without a proper externally mounted microphone, GoPro cams are typically best just for recording video; sound is terrible due to the encasement and the vibration within the case. Since your exhaust creates a lot of deep tones, all you hear is the vibration of the camera inside the plastic.

Really, really nice exhaust, though.

lol i know. but they didn't leave room for a microphone on the case..
