This is the first Cherry Bomb Glasspack I have installed on one of my personal vehicles. I went from having the exhaust cut off behind the cat to this thing connecting from the cat to my muffler back tailpipe. Given the setup, it made my truck quieter. But it is quieter for the better. Its a very smooth clean sound now. It is temporarily installed with some local A-Zone muffler clamps and this has transformed my truck into something tolerable to drive. Well done.
