Invidia Gemini CBE & ERZ HFC Review (with db comparison)

You can hear it when you're outside the car or with the window open. It's not as noticeable when the windows are closed. All the flanges fit fine and bolts are tightened properly. Bluestyle, is that what you describe as hiss and rasp? I would describe what I hear as a rattle. It's getting annoying. Anyone else notice this?

Did you install this your self or did a shop do it? Do you have a CBE or is it still stock?
