Question Direct Flow Lid

I just recently installed a Direct Flow Lid and noticed that when I get on it I hear a whistle like sound. When I drive normal I dont hear it at all. I checked for leaks and made sure everything is tight. Is this normal?

Usually it is normal. Due to the design, some lids will make a whistling noise.

Thats why you gain HP with a lid, you lose the
baffles inside that prevent it.

I was wondering how you hear a little whistle with a exhaust setup like you have?
