I have put two audio clips of my open exhaust on this link. One link is of the car starting and the other is of the car running with open exhaust. The sound is true but its not as loud on the video. In person its extremely loud and shakes the car at WOT.

Well here is the link.

Try it again I had a type in the link.

 

LOL, brings back memories of my 67 Chevy II when it had a straight 6.

 

Pretty unique sound
