Meh, I have to repair/replace my supercharger, and was considering a Lysholm (screw), but I dread the thought of my car sounding like a "fire engine siren"...there are scilencer kits for it however, but whatever floats your boat.
I don't know, I just like the sound. Never really heard it described as a fire engine siren...more of a banshee being violated in the worst way.
I only have a roots style, but even that sound is addictive. I'd probably spend a lot less of fuel every month if I could break the habit of stepping on the gas just to hear the supercharger wail.
