^^I used to notice mine a lot, but now I'm used to it plus I have a louder exhaust. I hardly ever notice it now

Im pretty used to it now too, ive had 2 CAIs for a total of probably 4 years, I was just curious if I may have had a leak. My exhaust doesnt cover up much, its the Flowmaster 60 Delta Flow...

My Car is VERY loud and I can hear the hiss between shifts over my exhaust now.

So far I cant notice anything in between shifts. The only time I really hear my intake is when I jump on it pretty hard, but even then I can barely hear it.

I've noticed that there isn't much intake noise below 3k, but once above 3500rpms you can tell a huge difference in intake noise.

i think the IMRC opens up around that RPM might explain it?

The 2.0 wouldn't have the runner control like the 2.3 would.
