Hey I know there are like a million videos of exhausts that have been put up in this thread already, but I thought I would make my contribution.
I did a sorta long video and posted it to facebook (I'll make something better in the future that isn't so darned long for youtube another day) and I thought I would share.
It more or less has everything in there from Slow start, casual neighborhood driving, screeching start, high revs, ect. I thought it would be a nice full experience. This was taken with my GoPro that I slapped to my rear bumper. Like I said, I'll probably make something nicer in the future. But for now enjoy 11 minutes of COBB noises. (you can also hear my Boomba BOV adapter.)
