Lowest average MPG

This reminds me when I was younger I had an aftermarket exhaust and a vented blow-off valve installed thus my MPG's fell to the floor. For a while, I was thinking that the "extra power" was making my car more thirsty. The reality is that later on in life, I realized that I was driving like a mad man since I wanted to hear at all times my new exhaust and blow-off valve combo and I wanted the entire town to hear it as well. So it was not the "extra power" what was burning more gas but it was my driving style since I was driving harder than normal just to be loud and obnoxious, but to me that was still considered "normal" driving.
Cheers!!!
