Problem with CAI???

I had a CAI installed 1 week ago and everything was great but now it lost the nice deep sound it had before. I can now only get a deep throaty sound in 4th & 5th gear between 4000 & 5000rpm. What’s wrong? I can’t seem to see anything wrong.

I’ve tried searching but haven’t found an answer to this question.

Thats normal, there is a sound change :wink:
