What is the black thing on the top of my LLY that says 6.6? I took it off the other day to install a boost controller from PPE, and it seemed to be just an empty piece of plastic. What good does it do, if any, and what would happen if I removed it and capped the outlet in the intake elbow or whatever it's called? Thanks

It's a turbo resonator, designed to keep the turbo "quieter". You can remove it and put a 2" test plug in it.

Why would you want a quieter turbo? Any chance of that plug getting sucked in? Will it do anything more than make the turbo louder, like increase airflow or something?

Most people want quiet. It won't suck a test plug thru it. It may whistle just a tiny bit more, but it does nothing more.

If your uneasy about your plug falling through put a little thread lock on there. Just to make sure. I did this to mine and it doesn't move at all.
