No it is not really super loud, It was probably an exageration.
You could barely hear the car before though. At idle it is alright. just pops a little. It just sounds VERY raspy at certain ranges. I am guessing 1200-2200RPM.
But my only question I am really concerned about is CAN a cat be installed backwards?
