Ladies and gents, I've been away a while, but I have a little something I'm curious about. I usually have the stereo up so I'd never hear it, but I hear what almost sounds like a gurgling sound, (sorta bees in a can) when I'm on the gas. Kinda faint, but it's there and I don't remember hearing it before. Car pulls fine runs well, but that can't be a good thing.

Potential possbilities? I was thinking intake turbulence or maybe the Y-pipe, but it's a Cattman so it would be unexpected. Can't really hear it on blocks in neutral. Thanks in advance
